Call for Papers
Scope of the Workshop
Stochastic local search (SLS) algorithms are among the most powerful techniques for solving computationally hard problems in many areas of computing science, operations research and engineering. SLS techniques range from rather simple constructive and iterative improvement algorithms to general-purpose SLS methods, also widely known as metaheuristics, such as ant colony optimization, evolutionary computation, iterated local search, memetic algorithms, simulated annealing, tabu search and variable neighbourhood search.
In recent years, it has become evident that the development of effective SLS algorithms is a complex engineering process that typically combines aspects of algorithm design and implementation with empirical analysis and problem-specific background knowledge. The difficulty of this process is in part due to the complexity of the problems being tackled and in part due to the large number of degrees of freedom researchers and practitioners face when developing SLS algorithms.
This development process needs to be assisted by a sound methodology that adresses the issues arising in the phases of algorithm design, implementation, tuning and experimental evaluation. In addition, more research is required to understand which SLS techniques are best suited for particular problem types and to better understand the relationship between algorithm components, parameter settings, problem characteristics and performance.
The three-day workshop will be held in Brussels, Belgium, on 6-8 September 2007.
Relevant Research Areas
The aim of this workshop is to stress the importance of an integration of relevant aspects of SLS research into a more coherent engineering methodology and to bring together researchers that work in various fields, including computing science, operations research, metaheuristics, algorithmics, statistics and application areas.
SLS 2007 solicits contributions dealing with any aspect of engineering stochastic local search algorithms. Typical, but not exclusive, topics of interest are:
- Methodological developments for the implementation of SLS algorithms (engineering procedures, integration of tools in the SLS engineering process, ...)
- In-depth experimental studies of SLS algorithms (behavior of SLS algorithms, comparison of SLS algorithms, ...), problem characteristics (search space analysis, ...) and their impact on algorithm performance.
- Tools for the assistance in the development process of SLS algorithms (software libraries, automatic and semi-automatic tuning procedures, learning techniques, ...).
- Case studies in the principled development of well designed SLS algorithms for practically relevant problems.
- Aspects that become relevant when moving from "classical" NP-hard problems to those including multiple objectives, stochastic information or dynamically changing data.
- New algorithmic developments (usage of AI/OR techniques, large scale neighbourhood searches, new SLS methods, data structures, distributed algorithms, ...)
- Theoretical analysis of SLS behaviour and their impact on algorithm design (analysis of operators, dynamic behaviour of SLS algorithms, ...)
