Title: Evaluating the Swarm Metaphor based Heuristics for Continuous Optimization - Modern Performance Measures and the (Non-parametric) Statistical Perspectives
Dr. Swagatam Das (Electronics and Communication Sciences Unit of the Indian Statistical Institute, Kolkata, India.)
Numerous metaheuristics have been proposed based on the life supporting activity of the swarming creatures in nature for solving optimization problems involving continuous search spaces. However, whether these algorithms will survive in the long run or whether their names will remain stipulated within the world of paper writing - this issue largely depends on the ease of implementation and efficiency in solving practical optimization problems. Most of the pioneering papers on swarm intelligence based metaheuristics generally exhibit the efficiency of the algorithm on a set of synthetic benchmark functions which are supposed to capture the different aspects of the real world optimization problems. This talk will focus on the benchmarking procedures adopted for comparing different metaheuristics meaningfully. The talk will elaborate on modern performance measures, design of experiments and provide some guidelines for selecting the suitable metaheuristic for solving a domain-specific problem. It will also discuss some recent non-parametric hypothesis test procedures to evaluate the comparative results. Finally some shortcomings of the modern statistical benchmarking procedures will be highlighted along with the discussion on some important future research directions.
