AB - In this chapter we will focus on the combination of evolutionary computation techniques and constraint satisfaction problems. Constraint Programming (CP) is another approach to deal with constraint satisfaction problems. In fact, it is an important prelude to the work covered here as it advocates itself as an alternative approach to programming (Apt). The first step is to formulate a problem as a CSP such that techniques from CP, EC, combinations of the two (c.f., Hybrid) or other approaches can be deployed to solve the problem. The formulation of a problem has an impact on its complexity in terms of effort required to either find a solution or proof no solution exists. It is therefore vital to spend time on getting this right. Main differences between CP and EC. CP defines search as iterative steps over a search tree where nodes are partial solutions to the problem where not all variables are assigned values. The search then maintain a partial solution that satisfies all variables assigned values. Instead, in EC most often solver sample a space of candidate solutions where variables are all assigned values. None of these candidate solutions will satisfy all constraints in the problem until a solution is found. Another major difference is that many constraint solvers from CP are sound whereas EC solvers are not. A solver is sound if it always finds a solution if it exists.

AB - Part II: "Data-intensive Knowledge Discovery", focuses on the needs of data-analysis experts. It illustrates the problem-solving strategies appropriate for a data-rich world, without delving into the details of underlying technologies. It should engage and inform data-analysis specialists, such as statisticians, data miners, image analysts, bio-informaticians or chemo-informaticians, and generate ideas pertinent to their application areas. Chapter 5: "Data-intensive Analysis", introduces a set of common problems that data-analysis experts often encounter, by means of a set of scenarios of increasing levels of complexity. The scenarios typify knowledge discovery challenges and the presented solutions provide practical methods; a starting point for readers addressing their own data challenges.

AB - Chapter 3: "The data-intensive survival guide", presents an overview of all of the elements of the proposed data-intensive strategy. Sufficient detail is presented for readers to understand the principles and practice that we recommend. It should also provide a good preparation for readers who choose to sample later chapters. It introduces three professional viewpoints: domain experts, data-analysis experts, and data-intensive engineers. Success depends on a balanced approach that develops the capacity of all three groups. A data-intensive architecture provides a flexible framework for that balanced approach. This enables the three groups to build and exploit data-intensive processes that incrementally step from data to results. A language is introduced to describe these incremental data processes from all three points of view. The chapter introduces ‘datascopes’ as the productized data-handling environments and ‘intellectual ramps’ as the ‘on ramps’ for the highways from data to knowledge.

AB - Part I: Strategies for success in the digital-data revolution, provides an executive summary of the whole book to convince strategists, politicians, managers, and educators that our future data-intensive society requires new thinking, new behavior, new culture, and new distribution of investment and effort. This part will introduce the major concepts so that readers are equipped to discuss and steer their organization’s response to the opportunities and obligations brought by the growing wealth of data. It will help readers understand the changing context brought about by advances in digital devices, digital communication, and ubiquitous computing. Chapter 1: The digital-data challenge, will help readers to understand the challenges ahead in making good use of the data and introduce ideas that will lead to helpful strategies. A global digital-data revolution is catalyzing change in the ways in which we live, work, relax, govern, and organize. This is a significant change in society, as important as the invention of printing or the industrial revolution, but more challenging because it is happening globally at lnternet speed. Becoming agile in adapting to this new world is essential.

AB - Background: Advances in DNA Microarray devices and next-generation massively parallel DNA sequencing platforms have led to an exponential growth in data availability but the arising opportunities require adequate computing resources. High Performance Computing (HPC) in the Cloud offers an affordable way of meeting this need. Objectives: Bioconductor, a popular tool for high-throughput genomic data analysis, is distributed as add-on modules for the R statistical programming language but R has no native capabilities for exploiting multi-processor architectures. SPRINT is an R package that enables easy access to HPC for genomics researchers. This paper investigates: setting up and running SPRINT-enabled genomic analyses on Amazon’s Elastic Compute Cloud (EC2), the advantages of submitting applications to EC2 from different parts of the world and, if resource underutilization can improve application performance. Methods: The SPRINT parallel implementations of correlation, permutation testing, partitioning around medoids and the multi-purpose papply have been benchmarked on data sets of various size on Amazon EC2. Jobs have been submitted from both the UK and Thailand to investigate monetary differences. Results: It is possible to obtain good, scalable performance but the level of improvement is dependent upon the nature of algorithm. Resource underutilization can further improve the time to result. End-user’s location impacts on costs due to factors such as local taxation. Conclusions: Although not designed to satisfy HPC requirements, Amazon EC2 and cloud computing in general provides an interesting alternative and provides new possibilities for smaller organisations with limited funds.

AB - Scientific gateways in the form of web portals are becoming the popular approach to share knowledge and resources around a topic in a community of researchers. Unfortunately, the development of web portals is expensive and requires specialists skills. Commercial and more generic web portals have a much larger user base and can afford this kind of development. Here we present two solutions that address this problem in the area of portals for scientific computing; both take the same approach. The whole process of designing, delivering and maintaining a portal can be made more cost-effective by generating a portal from a description rather than programming in the traditional sense. We show four successful use cases to show how this process works and the results it can deliver.

AB - Quantitative qPCR is a routinely used method for the accurate quantification of nucleic acids. Yet it may generate erroneous results if the amplification process is obscured by inhibition or generation of aberrant side-products such as primer dimers. Several methods have been established to control for pre-processing performance that rely on the introduction of a co-amplified reference sequence, however there is currently no method to allow for reliable control of the amplification process without directly modifying the sample mix. Herein we present a statistical approach based on multivariate analysis of the amplification response data generated in real-time. The amplification trajectory in its most resolved and dynamic phase is fitted with a suitable model. Two parameters of this model, related to amplification efficiency, are then used for calculation of the Z-score statistics. Each studied sample is compared to a predefined reference set of reactions, typically calibration reactions. A probabilistic decision for each individual Z-score is then used to identify the majority of inhibited reactions in our experiments. We compare this approach to univariate methods using only the sample specific amplification efficiency as reporter of the compatibility. We demonstrate improved identification performance using the multivariate approach compared to the univariate approach. Finally we stress that the performance of the amplification compatibility test as a quality control procedure depends on the quality of the reference set.

AB - More data will be produced in the next five years than in the entire history of human kind, a digital deluge that marks the beginning of the Century of Information. Through a year‐long consultation with UK researchers, a coherent strategy has been developed, which will nurture Century‐of‐Information Research (CIR); it crystallises the ideas developed by the e‐Science Directors’ Forum Strategy Working Group. This paper is an abridged version of their latest report which can be found at: http://wikis.nesc.ac.uk/escienvoy/Century_of_Information_Research_Strategy which also records the consultation process and the affiliations of the authors. This document is derived from a paper presented at the Oxford e‐Research Conference 2008 and takes into account suggestions made in the ensuing panel discussion. The goals of the CIR Strategy are to facilitate the growth of UK research and innovation that is data and computationally intensive and to develop a new culture of ‘digital‐systems judgement’ that will equip research communities, businesses, government and society as a whole, with the skills essential to compete and prosper in the Century of Information. The CIR Strategy identifies a national requirement for a balanced programme of coordination, research, infrastructure, translational investment and education to empower UK researchers, industry, government and society. The Strategy is designed to deliver an environment which meets the needs of UK researchers so that they can respond agilely to challenges, can create knowledge and skills, and can lead new kinds of research. It is a call to action for those engaged in research, those providing data and computational facilities, those governing research and those shaping education policies. The ultimate aim is to help researchers strengthen the international competitiveness of the UK research base and increase its contribution to the economy. The objectives of the Strategy are to better enable UK researchers across all disciplines to contribute world‐leading fundamental research; to accelerate the translation of research into practice; and to develop improved capabilities, facilities and context for research and innovation. It envisages a culture that is better able to grasp the opportunities provided by the growing wealth of digital information. Computing has, of course, already become a fundamental tool in all research disciplines. The UK e‐Science programme (2001–06)—since emulated internationally—pioneered the invention and use of new research methods, and a new wave of innovations in digital‐information technologies which have enabled them. The Strategy argues that the UK must now harness and leverage its own, plus the now global, investment in digital‐information technology in order to spread the benefits as widely as possible in research, education, industry and government. Implementing the Strategy would deliver the computational infrastructure and its benefits as envisaged in the Science & Innovation Investment Framework 2004–2014 (July 2004), and in the reports developing those proposals. To achieve this, the Strategy proposes the following actions: 1. support the continuous innovation of digital‐information research methods; 2. provide easily used, pervasive and sustained e‐Infrastructure for all research; 3. enlarge the productive research community which exploits the new methods efficiently; 4. generate capacity, propagate knowledge and develop skills via new curricula; and 5. develop coordination mechanisms to improve the opportunities for interdisciplinary research and to make digital‐infrastructure provision more cost effective. To gain the best value for money strategic coordination is required across a broad spectrum of stakeholders. A coherent strategy is essential in order to establish and sustain the UK as an international leader of well‐curated national data assets and computational infrastructure, which is expertly used to shape policy, support decisions, empower researchers and to roll out the results to the wider benefit of society. The value of data as a foundation for wellbeing and a sustainable society must be appreciated; national resources must be more wisely directed to the collection, curation, discovery, widening access, analysis and exploitation of these data. Every researcher must be able to draw on skills, tools and computational resources to develop insights, test hypotheses and translate inventions into productive use, or to extract knowledge in support of governmental decision making. This foundation plus the skills developed will launch significant advances in research, in business, in professional practice and in government with many consequent benefits for UK citizens. The Strategy presented here addresses these complex and interlocking requirements.

AB - FireGrid is a modern concept that aims to leverage a number of modern technologies to aid fire emergency response. In this paper we provide a brief introduction to the FireGrid project. A number of different technologies such as wireless sensor networks, grid-enabled High Performance Computing (HPC) implementation of fire models, and artificial intelligence tools need to be integrated to build up a modern fire emergency response system. We propose a system architecture that provides the framework for integration of the various technologies. We describe the components of the generic FireGrid system architecture in detail. Finally we present a small-scale demonstration experiment which has been completed to highlight the concept and application of the FireGrid system to an actual fire. Although our proposed system architecture provides a versatile framework for integration, a number of new and interesting research problems need to be solved before actual deployment of the system. We outline some of the challenges involved which require significant interdisciplinary collaborations.

AB - This paper presents findings from the e-Uptake project which aims to widen the uptake of e-Infrastructure Services for research. We focus specifically on the identification of barriers and enablers of uptake and the taxonomy developed to structure our findings. Based on these findings, we describe the development of a number of interventions such as training and outreach events, workshops and the deployment of a UK 'one-stop-shop' for support and event information as well as training material. Finally, we will describe how the project relates to other ongoing community engagement efforts in the UK and worldwide. Introduction Existing investments in e-Science and Grid computing technologies have helped to develop the capacity to build e-Infrastructures for research: distributed, networked, interoperable computing and data resources that are available to underpin a wide range of research activities in all research disciplines. In the UK, the Research Councils and the JISC are funding programmes to support the development of essential components of such infrastructures such as National Grid Service (www.ngs.ac.uk) or the UK Access Management Federation (www.ukfederation.org.uk) as well as discipline-specific efforts to build consistent and accessible instantiations of e-Infrastructures, for example the e- Infrastructure for the Social Sciences (Daw et al. 2007). These investments are complemented by an active programme of community engagement (Voss et al. 2007). As part of the community engagement strand of its e-Infrastructure programme, JISC has funded the e-Uptake project, a collaboration between the ESRC National Centre for e-Social Science at the University of Manchester, the Arts & Humanities e-Science Support Centre at King's College London and the National e-Science Centre at the University of Edinburgh. In this paper we present the project's activities to date to widen the uptake of e-Infrastructure services by eliciting information about the barriers to and enablers of uptake, developing adequate interventions such as training and outreach events, running workshops and the deploying a UK 'one-stop-shop' for support and event information as well as training material.

AB - The Multi Interface-Device Binding (MID-B) System enhances a multimodal interaction in a virtual-device environment. The system promises to overcome the drawbacks of classic multimodal interaction. In the classic sense, multimodality uses a strategy of simultaneously utilising several modalities generally offered on a single device. In contrast, the MID-B’s mechanism gets multimodality out of the solitary-device scenario. In MID-B, a ‘controller- device’ (UE_C) is aware of the availability of various devices in the vicinity, each of which may host one or more user interfaces (modalities). The capabilities of each of the co-located devices, together with the context in which the user acts, is exploited to dynamically customise the interface services available. This paper describes the MID-B architecture and its mechanisms to collect and exploit device and user context information to dynamically adapt the user interfaces.

AB - The UK and wider international e-Research initiatives are entering a critical phase in which they need to move from the development of the basic underlying technology, demonstrators, prototypes and early applications to wider adoption and the development of stable infrastructures. In this paper we will review existing work on studies of infrastructure and community development, requirements elicitation for existing services as well as work within the arts and humanities and the social sciences to establish e-Research in these communities. We then describe two projects recently funded by JISC to study barriers to adoption and responses to them as well as use cases and service usage models.

AB - Analyses of disasters such as the Piper Alpha explosion (Sylvester-Evans and Drysdale, 1998), the World Trade Centre collapse (Torero et al, 2002, Usmani et al, 2003) and the fires at Kings Cross (Drysdale et al, 1992) and the Mont Blanc tunnel (Rapport Commun, 1999) have revealed many mistaken decisions, such as that which sent 300 fire-fighters to their deaths in the World Trade Centre. Many of these mistakes have been attributed to a lack of information about the conditions within the fire and the imminent consequences of the event. E-Science offers an opportunity to significantly improve the intervention in fire emergencies. The FireGrid Consortium is working on a mixture of research projects to make this vision a reality. This paper describes the research challenges and our plans for solving them.

The approach is based on the metaphor of transitions in complexity discussed in the context of evolutionary biology. Partially defined solutions interact and evolve into aggregations until a full solution for the problem at hand is found. The impact of the initial population on the outcome and the dynamics of the process is evaluated using the domain of binary constraint satisfaction problems.

AB - We introduce the concept of fruitful regions in a dynamic routing context: regions that have a high potential of generating loads to be transported. The objective is to maximise the number of loads transported, while keeping to capacity and time constraints. Loads arrive while the problem is being solved, which makes it a real-time routing problem. The solver is a self-adaptive evolutionary algorithm that ensures feasible solutions at all times. We investigate under what conditions the exploration of fruitful regions improves the effectiveness of the evolutionary algorithm.

AB - Data Access and Integration (DAI) of data resources, such as relational and XML databases, within a Grid context. Project members also participate in the development of DAI standards through the GGF DAIS WG. The standards that emerge through this effort will be adopted by OGSA-DAI once they have stabilised. The OGSA-DAI developers are also engaging with a growing user community to gather their data and functionality requirements. Several large projects are already using OGSA-DAI to provide their DAI capabilities. This paper presents a status report on OGSA-DAI activities since the last AHM and announces future directions. The OGSA-DAI software distribution and more information about the project is available from the project website at http://www.ogsadai.org.uk/.

AB - The OGSA-DAI project has been producing Grid-enabled middleware for almost two years now, providing data access and integration capabilities to data resources, such as databases, within an OGSA context. In these two years, OGSA-DAI has been tracking rapidly evolving standards, managing changes in software dependencies, contributing to the standardisation process and liasing with a growing user community together with their associated data requirements. This process has imparted important lessons and raised a number of issues that need to be addressed if a middleware product is to be widely adopted. This paper examines the experiences of OGSA-DAI in implementing proposed standards, the likely impact that the still-evolving standards landscape will have on future implementations and how these affect uptake of the software. The paper also examines the gathering of requirements from and engagement with the Grid community, the difficulties of defining a process for the management and publishing of metadata, and whether relevant standards can be implemented in an efficient manner. The OGSA-DAI software distribution and more details about the project are available from the project Web site at http://www.ogsadai.org.uk/.

AB - The UK e-Science Programme is a £250M, 5 year initiative which has funded over 100 projects. These application-led projects are under-pinned by an emerging set of core middleware services that allow the coordinated, collaborative use of distributed resources. This set of middleware services runs on top of the research network and beneath the applications we call the ‘Grid’. Grid middleware is currently in transition from pre-Web Service versions to a new version based on Web Services. Unfortunately, only a very basic set of Web Services embodied in the Web Services Interoperability proposal, WS-I, are agreed by most IT companies. IBM and others have submitted proposals for Web Services for Grids - the Web Services ResourceFramework and Web Services Notification specifications - to the OASIS organisation for standardisation. This process could take up to 12 months from March 2004 and the specifications are subject to debate and potentially significant changes. Since several significant UK e-Science projects come to an end before the end of this process, the UK therefore needs to develop a strategy that will protect the UK’s investment in Grid middleware by informing the Open Middleware Infrastructure Institute’s (OMII) roadmap and UK middleware repository in Southampton. This paper sets out an evolutionary roadmap that will allow us to capture generic middleware components from projects in a form that will facilitate migration or interoperability with the emerging Grid Web Services standards and with on-going OGSA developments. In this paper we therefore define a set of Web Services specifications - that we call ‘WS-I+’ to reflect the fact that this is a larger set than currently accepted by WS-I – that we believe will enable us to achieve the twin goals of capturing these components and facilitating migration to future standards. We believe that the extra Web Services specifications we have included in WS-I+ are both helpful in building e-Science Grids and likely to be widely accepted.

AB - This paper describes the experiences of the OGSA-DAI team in designing and building a database access layer using the OGSI and the emerging DAIS GGF recommendations. This middleware is designed for enabling other UK e-Science projects that require database access and providing the basic primitives for higher-level services such as Distributed Query Processing. OGSA-DAI also intends to produce one of the required reference implementations of the DAIS specification once this becomes a proposed recommendation and, until then, scope out their ideas, provide feedback as well as directly contributing to the GGF working group. This paper enumerates the issues that have arisen in tracking the DAIS and OGSI specifications whilst developing a software distribution using the Grid services model; trying to serve the needs of the various target communities; and using the Globus Toolkit OGSI core distribution.

AB - This document is intended to provide the context for developing Grid data service standard recommendations within the Global Grid Forum. It defines the generic requirements for accessing and integrating persistent structured and semi-structured data. In addition, it defines the generic functionalities which a Grid data service needs to provide in supporting discovery of and controlled access to data, in performing data manipulation operations, and in virtualising data resources. The document also defines the scope of Grid data service standard recommendations which are presented in a separate document.

AB - In this paper we present a new tool to measure the efficiency of evolutionary algorithms by storing the whole searched space of a run, a process whereby we gain insight into the number of distinct points in the state space an algorithm has visited as opposed to the number of function evaluations done within the run. This investigation demonstrates a certain inefficiency of the classical mutation operator with mutation-rate 1/l, where l is the dimension of the state space. Furthermore we present a model for predicting this inefficiency and verify it empirically using the new tool on binary constraint satisfaction problems.

AB - PJama1 is the latest version of an orthogonally persistent platform for Java. It depends on a new persistent object store, Sphere, and provides facilities for class evolution. This evolution technology supports an arbitrary set of changes to the classes, which may have arbitrarily large populations of persistent objects. We verify that the changes are safe. When there are format changes, we also convert all of the instances, while leaving their identities unchanged. We aspire to both very large persistent object stores and freedom for developers to specify arbitrary conversion methods in Java to convey information from old to new formats. Evolution operations must be safe and the evolution cost should be approximately linear in the number of objects that must be reformatted. In order that these conversion methods can be written easily, we continue to present the pre-evolution state consistently to Java executions throughout an evolution. At the completion of applying all of these transformations, we must switch the store state to present only the post-evolution state, with object identity preserved. We present an algorithm that meets these requirements for eager, total conversion. This paper focuses on the mechanisms built into Sphere to support safe, atomic and scalable evolution. We report our experiences in using this technology and include a preliminary set of performance measurements.

AB - In this paper we describe how the Stepwise Adaptation of Weights (SAW) technique can be applied in genetic programming. The SAW-ing mechanism has been originally developed for and successfully used in EAs for constraint satisfaction problems. Here we identify the very basic underlying ideas behind SAW-ing and point out how it can be used for different types of problems. In particular, SAW-ing is well suited for data mining tasks where the fitness of a candidate solution is composed by `local scores' on data records. We evaluate the power of the SAW-ing mechanism on a number of benchmark classification data sets. The results indicate that extending the GP with the SAW-ing feature increases its performance when different types of misclassifications are not weighted differently, but leads to worse results when they are.

Binary data classification problems (with exactly two disjoint classes) form an important application area of machine learning techniques, in particular genetic programming (GP). In this study we compare a number of different variants of GP applied to such problems whereby we investigate the effect of two significant changes in a fixed GP setup in combination with two different evolutionary models
