1 Black Box Optimization Benchmarking 2010 (BBOB 2010)

In the last decades, numerous algorithms taking inspiration from nature have been proposed to handle continuous optimization problems: Evolution Strategies and Evolutionary Programming, real-coded Genetic Algorithms, Estimation of Distribution Algorithms, Differential Evolution, Particle Swarm Optimization, memetic algorithms, to name just a few. On the other hand, gradient-based, quasi-Newton algorithms, pattern search algorithms and more recently Derivative-Free-Optimization algorithms have been proposed and improved by applied mathematicians. Although comparisons of the performance of different optimizers are made in research studies, few optimizers are usually tested within a single work. Different works usually do not use the same experimental settings hampering their comparability, and often comparisons are biased to certain types of test functions: for a long time, most Evolutionary Algorithms have been tested mainly on separable problems.

The BBOB workshop pursues efforts for a comprehensive comparison of continuous search algorithms for single-objective black-box optimization. As a follow-up of BBOB at GECCO 2009, the workshop exploits the previously developed framework allowing to rigorously compare continuous optimizers for non-noisy and noisy optimization. Apart from minor adjustments, we provide the same testbed and experimental setting as last year. Participants will have access to data that have been submitted for BBOB 2009 and are provided with Python scripts to easily compare the performance of any two algorithms in detail. Participants are invited to submit a paper with the results of their algorithm of choice, and/or comparison with an algorithm from our database, and/or comparison of two or several algorithms. An overall analysis and comparison will be accomplished by the organizers and presented during the workshop together with the single presentations of each participant. A plenary discussion on future improvements will, among others, address the question, of how the testbed should evolve.

Evolutionary Computation and Multi-Agent Systems and Simulation (ECoMASS) - Fourth Annual Workshop

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 adapts 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 individual decisions. Similarly, most work in EC is concerned with how to engineer selective pressures to drive the evolution of individuals towards some desired goal. Multi-agent simulation (also called agent-based modeling) addresses the bottom-up issue of how collective behavior emerges from individual action. Likewise, the study of evolutionary dynamics 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 analogous processes. It is therefore natural to consider how 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.

Example Topics:

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 the 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

3 Evolutionary Computation Techniques for Constraint Handling

Evolutionary algorithms are often applied to difficult optimization problems where candidate solutions are subject to various constraints. There is a large body of practical guidelines and theoretical results about evolutionary algorithms in the context of constrained optimization. Closely related is the subject of constraint programming where some solution satisfying all constraints is sought. In both contexts evolutionary computation techniques can be and are applied to solve hard problems. The workshop intends to provide a forum for current research in these areas. Algorithmic techniques, case studies, theoretical and empirical analyses are all welcome. While focusing on handling constraints we intend to provide a forum for discussion, therefore allowing generous time slots for each presentation and ample time for discussions.

4 Entropy, Information and Complexity

Among the basic concepts and state variables of thermodynamics, ENTROPY plays a central role, explained by Boltzmann et al as statistical mechanics. Entropy and its complement [mutual] INFORMATION play key roles in the theory of communication by Shannon et al. COMPLEXITY and algorithmic information play the corresponding roles in the complexity theory of Kolmogorov et al.

All 3 of these theories are directly applicable to both natural biological evolution and evolutionary computation, but have generally been applied by neither theoreticians nor practitioners in the latter field. In recent years, a few papers have appeared, scattered across different venues. This workshop will bring together researchers with a common interest in applying these concepts systematically to evolutionary computation and learning.

The first half of the workshop will be a series of mini-tutorials on the related concepts and variables in the context of each of the 3 theories.

The second half of the workshop will be a series of presentations of papers describing original work using these concepts in evolutionary algorithm theory, design and application.

A formal, unified, information theoretic and thermodynamic framework of evolutionary computation and learning would be of immense value to theorists and practitioners, so prospects for this, and any other topics of interest to the participants, will be brainstormed.

His PhD thesis, explores the connection between information theory and optimisation problems in the black box scenario. It consists of two parts: (1) a formal part which quantifies the amount of information that a landscape (problem in the black box scenario) contains and accordingly, using the notion of Kolmogorov complexity gives upper and lower bounds to performance, and (2) a part based on a linear approximation to the performance of a search algorithm which investigates the alignment of particular search algorithms with problems.



 

5 Graduate Student workshop
This full day workshop will involve presentations by approximately 10 selected students pursing research in some aspect of evolutionary computation. Students will make 15-20 minute presentations to an audience that will include a 'mentor' panel of established researchers in evolutionary computation. Presentations will be followed by a 10 minute question and discussion period led by the mentor panel.

Students will also be invited present their work as a poster at the evening Poster Session - an excellent opportunity to network with industry and academic members of the community.

The goal of this workshop is to assist students regarding their research: research methodology, goals, and plans. Students will also receive feedback on their presentation style. Other attendees will benefit by learning about current research, engaging in technical discussions and meeting researchers with related interests. Other students are encouraged to attend as a means of strengthening their own
research.

The group of presenting students will be chosen with the intent of creating a diverse group of students working on a broad range of topic areas.

Awards will be presented for best work and best presentation.

6 Thirteenth 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 to on-line control. Classifier systems are a very active area of research, with many 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.

This will be the 13th edition of the workshop, which was initiated in 1992, held at the NASA Johnson Space Center in Houston, Texas. Since 1999 the workshop has been held yearly in conjunction with PPSN in 2000 and 2002 and with GECCO in 1999, 2001 and from 2003 to 2009

Topics of interests include but are not limited to:

Paradigms of LCS (Michigan, Pittsburgh, ...)
Theoretical developments (behavior, scalability and learning bounds, ...)
Representations (binary, real-valued, oblique, non-linear, fuzzy, ...)
Types of target problems (single-step, multiple-step, regression/function approximation,...) - System enhancements (competent operators, problem structure identification and linkage learning, ...)
LCS for Cognitive Control (architectures, emergent behaviours, ...)
Applications (data mining, medical domains, bioinformatics, ...)

7 Medical Applications of Genetic and Evolutionary Computation (MedGEC)

MedGEC 2010 is the sixth GECCO Workshop on the application of genetic and evolutionary computation (GEC) to problems in medicine and healthcare.

A dedicated workshop at GECCO provides a much needed focus for medical related applications of EC, not only providing a clear definition of the state of the art, but also support to practitioners for whom GEC might not be their main area of expertise or experience.

The Workshop has two main aims:
(i) to provide delegates with examples of the current state of the
art of applications of GEC to medicine.
(ii) to provide a forum in which researchers can discuss and
exchange ideas, support and advise each other in theory and practice.

Subjects will include (but are not limited to) applications of GEC to:

Medical imaging
Medical signal processing
Medical text analysis
Clinical diagnosis and therapy
Data mining medical data and records
Clinical expert systems
Modelling and simulation of medical processes
Drug description analysis
Patient-centric care

New for MedGEC 2010 will be a presentation detailing the range of medical applications to which GEC has been applied.

8 Optimization by Building and Using Probabilistic Models (OBUPM-2010)

Genetic and evolutionary algorithms (GEAs) evolve a population of candidate solutions using two main operators: (1) selection and (2) variation. However, fixed, problem independent variation operators often fail to effectively exploit important features of high quality solutions obtained by selection to create novel, high-quality solutions. One way to make variation operators more effective is to replace traditional variation operators by the following two steps:

1. Estimate the distribution of the selected solutions on the basis of an adequate probabilistic model.

2. Generate a new population of candidate solutions by sampling from the distribution estimated.

Algorithms based on this principle are often called probabilistic model-building genetic algorithms (PMBGAs), estimation of distribution algorithms (EDAs) or iterated density estimation algorithms (IDEAs). The purpose of this workshop is to discuss recent advances in PMBGAs, theoretical and empirical results, applications of PMBGAs, and promising directions of future PMBGA research.

9 Symbolic Regression and Modeling Workshop

Symbolic Modeling is used to designate the search for symbolic descriptions, usually in the language of mathematics, to describe and predict numerical data in diverse fields such as industry, economics, finance and science.

Symbolic modeling captures the field of symbolic regression: a genetic programming based search technique for finding symbolic formulae on numerical data in order to obtain an accurate and concise description of that data in symbolic, mathematical form. In the evolutionary computation field it also captures learning classifier systems, if and when they are applied to obtain specific interpretable results in the field of interest.

Symbolic modeling can be defined as a set of techniques (including, but not limited to symbolic regression and learning classifier systems) and representations that try to find a mathematical description and prediction in some numerical space. This can be contrasted with numerical modeling such as (generalized) linear regression, neural networks, kernel regression and support vector machines.

The key discriminator of producing symbolic results over numerical results is the ability to interpret and analyze the results, leading either to acceptance by field experts, or to heightened understanding of the theory in the field of application. Interpretation is key, and the workshop will focus heavily on this.

The workshop will focus on advances in using symbolic modeling for real world problems in industry, economics, finance and science. Papers are sought that contribute to the state of the art in symbolic modeling, either through innovative applications, theoretical work on issues of generalization, size and comprehensibility of the results produced, and algorithmic improvements to make the techniques faster, more reliable and generally better controlled.

10 Theoretical Aspects of Evolutionary Multiobjective Optimization - Current Status and Future Trends

Evolutionary Multiobjective Optimization (EMO), i.e., the simultaneous optimization of 2 or more objective functions by means of bio-inspired search heuristics, has become one of the main research fields in evolutionary computation in recent years and as such also gained interest from the classical field of multicriteria decision making (MCDM). Together with its fast development in practice, also theoretical analyses of EMO gained more and more interest. Besides several theoretical papers at international conferences such as GECCO or FOGA, also the current special issue of the Evolutionary Computation Journal devoted to "Theoretical Aspects of Evolutionary Multi-Objective Optimization" underpins this development.

To foster the growing interest of theory in EMO, the workshop aims at bringing together theoreticians both working in the field of EMO and from single-objective optimization as well as EMO practitioners. Besides presenting the newest theoretical results about EMO, the workshop aims at identifying a broad list of challenging questions to be tackled in the near future for which a collaboration between theoreticians and practitioners is expected to be highly beneficial. In this regard, we would like to invite both theoreticians and practitioners to talk and discuss about the latest developments in the field of theoretical analysis of evolutionary multiobjective optimization. It is highly appreciated if challenging questions and interesting new research directions are identified. The workshop covers all theoretical topics of EMO, including but not limited to

convergence analysis
decision making
diversity mechanisms
experimental studies based on theoretical considerations
hybridized EMO approaches
indicator-based search
many-objective optimization
multiobjectivization
performance assessment
preference handling
runtime analyses (incl. approximation results)
set-based EMO
variation operators specific to the multiobjective case

13 Experimental Design and Statistical Analysis Workshop

This workshop is designed to be a hands-on companion to the Experimental Design and Statistics tutorials:

1. Statistical analysis for evolutionary computation (EC): Introduction (Mark Wineberg, Steffen Christensen)

2. Tuning and Experimental Analysis in EC: What We Still Have Wrong (Thomas Bartz-Beielstein, Mike Preuss)

This workshop will give you a chance to try out the various techniques learned in the tutorials in a controlled environment so you could then apply them to your own problems when you get back to your lab. Our field is becoming more and more rigorous in the application of appropriate experimental design and statistical analysis for any experiment being submitted the major conferences in the field. Make sure that you or your student’s have the experience you need to be able to perform a proper analysis. You supply your laptop; we will supply the tools and techniques. Parts of this workshop use “R”, a freely available language and environment for statistical computing and graphics. R provides a wide variety of statistical and graphical techniques. The software can be downloaded from http://cran.r-project.org.

The workshop will be presented at an introductory level and is meant for any EC researchers who want to compare their newly designed EC system with established EC systems to see if there is an improvement, or who want to determine which EC system performs better on their chosen problem; i.e., nearly everyone. It is vital, if our community is to be taken seriously, for us to continue to educate ourselves, and especially new Graduate students, on the statistical and experimental design techniques that are considered rigor for experiments performed in any field that is stochastic in nature, as is EC.

Topics Covered

1. Experimental Design: Factorial and space-filling designs, experimental setup and scope etc.

2. Statistical Analysis: Hypotheses testing, regression, analysis of variance (ANOVA), Bonferonni Post-hoc correction.

3. Sequential Parameter Optimization: Introduction to automatic and interactive tuning of algorithms. The sequential parameter optimization toolbox (SPOT) package for R is a toolbox for tuning and understanding simulation and optimization algorithms. SPOT includes methods for tuning based on classical regression and analysis of variance techniques; tree-based models such as CART and random forest; Gaussian process models (Kriging) and combinations of different meta-modeling approaches. This workshop exemplifies how SPOT can be used for automatic and interactive tuning.

Schedule

1. Intro Talk - orientation
2. Download relevant material. Installing an R system and the SPOT package on your computer
3. Design first experiment
4. Run first experiment
5. Analyze first experiment
6. Comparison: Interactive and automatic Tuning
7. Discussion, Q&A
