| - | ===== Graphical Tools for analysing Multi-Objective Data. ===== | ||
| - | |||
| - | In multi-objective problems, not only one objective function must be minimised but several, often conflicting, objectives must be taken into account. The result is often a set of solutions modelling the trade-off between the objectives of the problem. | ||
| - | |||
| - | The goal of this project is to develop graphical tools to interactively examine and compare the results of algorithms for multi-objective problems. | ||
| - | |||
| - | Required skills: The candidate should be well acquainted with programming in object oriented languages. | ||

| - | ===== Stochastic Local Search heuristics for solving NP-complete puzzles. ====== | ||
| - | |||
| - | This project is about single player games (puzzles) and the design of algorithms for tackling hard combinatorial optimisation problems. | ||
| - | Example puzzles are: [[http://en.wikipedia.org/wiki/Light_Up|Light Up]], [[http://en.wikipedia.org/wiki/Mastermind_(board_game)|Mastermind]], [[http://en.wikipedia.org/wiki/Minesweeper_(video_game)|Minesweeper]], etc. | ||
| - | |||
| - | The student will learn how to design and implement a Stochastic Local Search algorithm to solve NP-complete puzzles. The student will also learn how to analyse the performaces of the algorithm and perform statistically sound comparisons with the other algorithms available in literature. | ||
| - | |||
| - | Required skills: good knowledge of C or C++ programming. | ||

| - | ===== Analysis of Local Optima Networks for the Max-Clique problem. ====== | ||
| - | |||
| - | Stochastic Local Search algorithms search for optimal solutions in a large space of candidate solutions. Local Optima Networks (LON) are representations of search landscapes of combinatorial optimisation problems. In these networks, nodes are local optima of the problem, and edges are weighted transitions between the optima. These networks model in a more compact way the properties of the larger search spaces they represent. | ||
| - | |||
| - | The goal of this project is to build LON of small instances of the Maximum Clique (MC) problem, and measure properties that could illustrate the differences between instance families. | ||
| - | |||
| - | The MC problem is an NP-hard combinatorial optimisation problem that asks to find the biggest completely connected component of a graph. It has relevant applications in information retrieval, computer vision, social network analysis, computational biochemistry, bioinformatics and genomics. | ||

| - | ===== Applications of the Multi-objective ACO framework ===== | + | ===== Applications of a hybrid SLS algorithm framework ===== |
| - | We have recently developed a software framework of Ant Colony Optimization algorithms for multi-objective optimization problems. This framework has only been applied to a few problems. The goal of this project would be to extend this framework to other problems and compare its results with the methods proposed in the literature. The student will learn to solve multi-objective optimization problems with ACO algorithms, automatic configuration of optimization algorithms, and analysis and comparison of optimization algorithms for multi-objective problems. | + | We have recently developed a software framework from which hybrid stochastic local search algorithms can be designed automatically.

| - | ===== A graphical interface for the optimisation of Water Distribution Networks ===== | ||
| - | The [[http://iridia.ulb.ac.be/~manuel/doc/cec2005-presentation.pdf|optimization of the operations of Water Distribution Networks]] may save important amounts of energy and its associated costs, and, therefore, it is an important problem in practice. There are [[http://www.epa.gov/nrmrl/wswrd/dw/epanet.html|graphical tools and simulators]] available. In addition, several optimization methods based on [[http://iridia.ulb.ac.be/~manuel/doc/cec2005.pdf|evolutionary algorithms]] and [[http://dx.doi.org/10.1061/(ASCE)0733-9496(2008)134:4(337)|ant colony optimization]] have been proposed in the literature. The goal of this project is to integrate the optimization algorithms into a graphical environment that can be used by water engineers and operators. No knowledge about water distribution networks is necessary. The optimisation algorithms and toolkit libraries for handling water distribution networks will be available to the student. | ||

| - | The goal of this project is to explore the possibilities of using automatic configuration tools for fine-tuning an existing [[http://paradiseo.gforge.inria.fr/index.php?n=Paradiseo.MOEO|evolutionary multi-objective framework]]. The student will learn about automatic configuration tools, evolutionary algorithms for multi-objective optimization problems and analysis and comparison of multi-objective algorithms. | ||
