1.- Workshop on Problem Understanding and Real-World Optimisation

This workshop sees the joining of two related workshops to reflect the link between stronger methods in problem understanding and the significant importance of scientific approaches to tackling real-world optimisation problems. This workshop will address the wider topic of scientific methods for analysing and solving difficult and real problems currently faced by optimisation researchers.
The workshop will continue the themes of last year's GECCO-UP workshop and aims to provide a forum for the discussion and exploration of methods for the analysis, creation and synthesis of optimisation problems through both theoretical and experimental methods. A crucial aspect of this research is developing problems that reflect the complexity and idiosyncrasies of real-world optimisation problems. Therefore, the workshop will open with a session focused on real-world optimisation problems, in which speakers from both industry and academia discuss their experiences of what makes real-world problems difficult. The workshop as a whole provides an opportunity for discussion and interactions that might move towards bridging the gap between  those problems addressed by scientific research and the types of problem addressed by commercial optimisation software vendors.
Furthermore, the continued the ethos of open debate of the previous workshops will be upheld in a discussion session held at the end of the workshop which will give an opportunity for participants to discuss and present recently published research and position papers.

The following key areas of active research will be of specific interest (although submissions are not limited to these areas):

- creation of test problems;
- experimental methods for analysing and detecting problem landscapes;
- identifiers and metrics for describing problem features;
- spatial descriptors;
- problem space visualisation;
- difficulty and complexity analysis;
- analysis of dynamic problems;
- analysis of noisy problems;
- construction of problem taxonomies and theoretical foundations;
- development of new benchmark sets of data that include relevant real-world constraints to demonstrate relevance of academic techniques;
- metrics by which problems should be evaluated that are relevant to practitioners;
- methods for comparing algorithms that address concerns of practitioners;
- discussion of real-world problem constraints.

3.- Black Box Optimization Benchmarking 2013 (BBOB 2013)

Benchmarking of optimization algorithms is crucial to assess performance of optimizers quantitatively, understand weaknesses and strengths of each algorithm and is the compulsory path to test new algorithm designs. The black-box-optimization benchmarking workshop aims at benchmarking both stochastic and deterministic continuous optimization algorithms in an anytime scenario. The new edition will follow the BBOB 2009, 2010 and 2012 GECCO workshops ( Those previous editions have resulted in (1) collecting data of various optimizers (32 in 2009, 25 in 2010, 30 in 2012) that are now freely available for the entire community, (2) providing meaningful tools for the visualization of the comparative results, and (3) have established a standard for the benchmarking of algorithms. As a result the BBOB test-suite as well as the results published at the workshops have been used in various publications (independent from the workshop), the benchmarking procedure proposed is becoming a standard and the data collected have started to be used by statisticians to identify and classify properties of algorithms. The impact of the previous editions is visible in the EC community but also in the mathematical optimization community where BBOB results start now to be cited.

With a new edition, we would like to build on the success of the previous workshops and increase and diversify the data collection we already have. In addition we would like to focus on expensive optimization and collect data of optimizers that are especially tailored for problems where only a small budget of function evaluations is affordable. As for the previous editions, we will provide code for running experiments in different languages (C, Matlab, Java, R, Python) and postprocessing data.

Participants are invited to submit a paper with the results of an algorithm of their choice plus comparisons with algorithms from our database. They are also encouraged to use the existing database for statistical analyses or for designing a portfolio of algorithms. When data for all algorithms of the portfolio are available in the database, the performance of the portfolio can be provided by the postprocessing without conducting further experiments.

4.- Sixteenth International Workshop on Learning Classifier Systems

Since Learning Classifier Systems (LCSs) were introduced by Holland [1] as a way of applying evolutionary computation to machine learning problems, the LCS paradigm has broadened greatly into a framework encompassing many representations, rule discovery mechanisms, and credit assignment schemes. Current LCS applications range from data mining to automated innovation and on-line control. Classifier systems are a very active area of research, with newer approaches, in particular Wilson's accuracy-based XCS [2], receiving a great deal of attention. LCS are also benefiting from advances in reinforcement learning and other machine learning techniques.

5.- Evolutionary Computation Software Systems (EvoSoft)

Evolutionary computation (EC) methods are applied in many different domains. Therefore soundly engineered, reusable, flexible, user-friendly, and interoperable software systems are more than ever required to bridge the gap between theoretical research and practical application. However, due to the heterogeneity of the application domains and the large number of EC methods, the development of such systems is both, time consuming and complex. Consequently many EC researchers still implement individual and highly specialized software which is often developed from scratch, concentrates on a specific research question, and does not follow state of the art software engineering practices. By this means the chance to reuse existing systems and to provide systems for others to build their work on is not sufficiently seized within the EC community. In many cases the developed systems are not even publicly released, which makes the comparability and traceability of research results very hard.

This workshop enables EC researchers to exchange their ideas on how to develop and apply generic and reusable EC software systems and to present open and freely available solutions on which others can build their work on. Furthermore, the workshop should help to identify common efforts in the development of EC software systems and should highlight cooperation potentials and synergies between different research groups. It concentrates on the importance of high-quality software systems and professional software engineering in the field of EC and provides a platform for EC researchers to discuss the following and other related topics:

* development and application of generic and reusable EC software systems
* architectural and design patterns for EC software systems
* software modeling of EC algorithms and problems
* open-source EC software systems
* expandability, interoperability, and standardization
* comparability and traceability of research results
* graphical user interfaces and visualization
* comprehensive statistical and graphical results analysis
* parallelism and performance
* usability and automation
* comparison and evaluation of EC software systems

From 2005 to 2009 he worked as an associate professor for software project engineering and since 2009 as a full professor for complex software systems at the University of Applied Sciences Upper Austria, Campus Hagenberg, Austria. Dr. Wagner is one of the founders of the research group Heuristic and Evolutionary Algorithms Laboratory (HEAL) and is the project manager and head developer of the HeuristicLab optimization environment.


Michael Affenzeller
He has published several papers, journal articles and books dealing with theoretical and practical aspects of evolutionary computation, genetic algorithms, and meta-heuristics in general. In 2001 he received his PhD in engineering sciences and in 2004 he received his habilitation in applied systems engineering, both from the Johannes Kepler University Linz, Austria. Michael Affenzeller is professor at the University of Applied Sciences Upper Austria, Campus Hagenberg, and head of the research group Heuristic and Evolutionary Algorithms Laboratory (HEAL).

6.- Visualisation Methods in Genetic and Evolutionary Computation (VizGEC 2013)

The fourth workshop on Visualisation in Genetic and Evolutionary Computation (VizGEC 2013) provides an opportunity for researchers to promote current visualisation developments in the area of genetic and evolutionary computation. Visualisation is an important tool in this area, and particular topics of interest are:

* visualisation of the evolution of a synthetic genetic population;
* visualisation of algorithm operation;
* visualisation of problem landscapes;
* visualisation of multi-objective trade-off sets;
* the use of genetic and evolutionary techniques for visualising data;
* facilitating human steer of algorithms;
* novel technologies for visualisation within genetic and evolutionary computation;
* non-visual techniques for presenting results (e.g. audio and audio-visual).

The workshop will include the presentation of papers, however we hope to take advantage of the workshop format to allow researchers to demonstrate their visualisation tools. This is intended to enable participants to interact with visualisation tools at the forefront of the evolutionary computation field and encourage discussion. Previous years' workshops have been well attended and have featured a diverse selection of topics, which we hope to continue this year. We look forward to seeing you in Amsterdam.

David Walker
He is an Associate Research Fellow with the Department of Computer Science and the Centre for Water Systems at the University of Exeter. He recently submitted his PhD, the focus of which is the understanding of many-objective populations. A principal component of his thesis involves visualising such populations and he is particularly interested in how evolutionary algorithms can be used to enhance visualisation methods. More recently, his research has also investigated evolutionary methods for the data mining of many-objective populations. His general research interests include evolutionary problem solving, particularly machine learning problems, techniques for identifying preference information in data and visualisation methods.


Richard Everson
He is Associate Professor of Machine Learning at the University of Exeter. He has a degree in Physics from Cambridge University and a PhD in Applied Mathematics from Leeds University. He worked at Brown and Yale Universities on fluid mechanics and data analysis problems until moving to Rockefeller University, New York, to work on optical imaging and modelling of the visual cortex. After working at Imperial College, London, he joined the Computer Science department at Exeter University. His research interests lie in statistical pattern recognition, multi-objective optimisation and the links between them. Recent interests include the optimisation of the performance of classifiers, which can be viewed as a many-objective optimisation problem requiring novel methods for visualisation. Research on the construction of league tables has led to publications exploring the multi-objective nature and methods of visualising league tables.


Jonathan Fieldsend
He is Lecturer of Computer Science at the University of Exeter. He has a degree in Economics from Durham University, a Masters in Computational Intelligence from the University of Plymouth and a PhD in Computer Science from the University of Exeter. He has held postdoctoral positions as a research fellow (working on the interface of Bayesian modelling and optimisation) and as a business fellow (focusing on knowledge transfer to industry) prior to his appointment to an academic position at Exeter.

His research interests include multi- and many-objective optimisation, machine learning and statistical pattern recognition and the interface between these areas. Work in these fields has led to an interest in visualisation, which in turn has led to peer reviewed work on the application and comparison of existing visualisation techniques to new domains, and the investigation of novel visualisation techniques. He has been active within the evolutionary computation community as a reviewer and program committee member since 2003.

7.- Evolutionary Computation and Multi-Agent Systems and Simulation (ECoMASS) Seventh Annual Workshop

Genetic and evolutionary computation (EC) and multi-agent systems and simulation (MASS) both involve populations of agents. EC is a learning technique by which a population of individual agents adapt according to the selection pressures exerted by an environment; MASS seeks to understand how to coordinate the actions of a population of (possibly selfish) autonomous agents that share an environment so that some outcome is achieved. Both EC and MASS have top-down and bottom-up features: For example, some aspects of Multi-agent system engineering (e.g., mechanism design) are concerned with how top-down structure can constrain or influence individual decisions. Similarly, most work in EC is concerned with how to engineer selective pressures to drive the evolution of individual behavior towards some desired goal. Multi-agent simulation (sometimes called agent-based modeling (ABM)) addresses the bottom-up issue of how collective behavior emerges from individual action. Likewise, the study of evolutionary dynamics (particularly in coevolution) within EC often considers how population-level phenomena emerge from individual-level interactions. Thus, at a high level, we may view EC and MASS as examining and utilizing analogous processes. It is therefore natural to consider how knowledge gained within EC may be relevant to MASS, and vice versa; indeed, applications and techniques from one field have often made use of technologies and algorithms from the other field. Studying EC and MASS in combination is warranted and has the potential to contribute to both fields.

Topics relevant to the proposed workshop include, but are not limited to:

-Multi-agent systems and agent-based models utilizing evolutionary computation
-Optimization of multi-agent systems and agent-based models using evolutionary computation
-Evolutionary computation models which rely not on explicit fitness functions but rather implicit fitness functions defined by the relationship to other individuals / agents
-Applications utilizing MASS and EC in combination
-Biological agent-based models (usually called individual-based models) involving evolution
-Evolution of cooperation and altruism
-Genotypic representation of complex phenotypic strategies of MASS
-Evolutionary learning within MASS (including Baldwinian learning and phenotypic plasticity)
-Emergence and feedbacks
-Open-ended strategy spaces and evolution
-Adaptive individuals within evolving populations

Forrest Stonedahl
He is an Assistant Professor of Computer Science and Mathematics at Centre College.
His dissertation work focussed on the use of evolutionary algorithms to explore the effects of varying parameters in multi-agent simulations, and he has published on this topic at venues such as GECCO, AAMAS, and the AAAI fall symposium, and has also authored an open-source software package for performing this task. Forrest has also combined multi-agent systems with evolutionary computation in several earlier publications, including an agent-based model that used restrictive breeding networks for an evolutionary algorithm, and a novel network-based GA crossover operator inspired by a simple agent-based diffusion mechanism. In addition, Forrest has published on the evolution of rules for non-uniform cellular automata and the analysis of noisy fitness landscapes. Forrest's substantial experience with multi-agent simulation stems from his work at the Center for Connected Learning and Computer-Based Modeling at Northwestern University and his work contributing to the development of the NetLogo multi-agent modeling language and environment. He has been involved in a variety of agent-based modeling projects in application areas such as urban development (modeling land usage) and linguistics (language cascades in social networks). Forrest's other scholarly interests include studying dynamic processes on networks, emergence in complex adaptive systems, and computer science education.


William Rand
While doing his graduate work at the University of Michigan, William completed a dissertation under the guidance of John Holland and Rick Riolo on genetic algorithms and dynamic environments, which discusses applications of that work to the use of GAs in multi-agent systems. He also published six papers on the same topic which were featured at both GECCO and EuroGP. At the same time, he continued to develop his interest in modeling by working on a large scale agent-based model of suburban sprawl. William then went on to Northwestern University's Institute on Complex Systems (NICO), where he worked on developing the NetLogo programming language, an integrated development environment for agent-based modeling (ABM). While there he co-authored a textbook on ABM under contract with MIT Press. He is currently the Director for the Center for Complexity in Business at the University of Maryland where he is also an Assistant Professor in Marketing, Decision, Operations and Information Technology and Computer Science. William has become interested in using evolutionary computation techniques to generate and refine agent-based models, and has presented papers on this subject at Agent, Swarmfest, GECCO, the World Congress on Social Simulation (WCSS) and the North American Association for Computational Social and Organization Sciences (NAACSOS). Besides co-organizing ECoMASS at GECCO-2007, GECCO-2008, GECCO-2009, GECCO-2010, and GECCO-2011, he was also chair of all workshops for GECCO-2012.

9.- 3rd Workshop on Evolutionary Computation for the Automated Design of Algorithms

The main objective of this workshop is to discuss evolutionary computation methods for generating algorithms and/or hyper-heuristics. These methods have the advantage of producing solutions that are applicable to any instance of a problem domain, instead of a solution specifically produced to a single instance of the problem. The areas of application of these methods may include, for instance, data mining, machine learning, and optimization.

10.- Green and Efficient Energy Applications of Genetic and Evolutionary Computation

Global increases in living standards, diminishing natural resources and environmental concerns place energy amongst the most important global issues today. On the consumer side, there is an increasing need for more efficient, smart, uses of energy, be it in large-scale computing systems and data warehouses, in homes or in office buildings. On the producer side, there is a push toward the use of sustainable, green, energy sources, which often come in the form of less reliable sources such as wind energy. In addition, future energy systems are often envisioned to be "smart", consisting of massive amounts of small generators, such as solar panels, located at consumers, effectively turning consumers into potential producers whenever they have a surplus of energy. The management, control and planning of, and efficient use of energy in (future) energy systems brings about many important challenges. The aim of this workshop is to bring together researchers interested in addressing challenging issues related to the use of evolutionary computation for applications in (future) energy systems.

12.- Stack-based Genetic Programming

Since its introduction in the early 1990's, stack-based Genetic Programming has grown into a significant 
sub-field of GP through the independent work of multiple researchers. While generally characterized by 
the explicit use of stacks to support the evolution and evaluation of programs, there is significant 
diversity in the various stack-based approaches with respect to program expression, data typing, and 
evolutionary manipulation. The intent of this workshop is to provide a collaborative forum and 
discussion venue for practitioners of (and parties interested in) stack-based GP. In this first workshop, 
we will explore the current state of the art through a combination of paper presentations and extended 
discussions on subjects of interest to the stack-based GP community. Example topics may include the 
use of single versus multiple stacks, approaches for handling data types and data structures, program 
expression syntax, effectiveness of evolutionary methods, and problem space affinity. The forum will 
encourage participants to consider advantages and disadvantages of dissimilar approaches and to share 
examples of both failures and successes in the development, application, and advancement of stack-
based GP.
