报告摘要:

Evolutionary computation is a branch of studying biologically motivated computational paradigms which exert novel ideas and inspiration from natural evolution and adaptation. In recent years, one of the focuses has been advanced into the developing efficient and effective many-objective evolutionary algorithms. When encounter optimization problems with many objectives, nearly all designs perform poorly because of loss of selection pressure in fitness evaluation solely based upon Pareto optimality principle. In this talk, we will devote our attention to address three issues to complete the real-world applications at hand- visualization, performance measure and multi-criteria decision-making for the many-objective optimization. Visualization of population in a high-dimensional objective space throughout the evolution process presents an attractive feature that could be well exploited in designing many-objective evolutionary algorithms. A performance metric tailored specifically for many-objective optimization is critically needed, preventing various artifacts of existing performance metrics violating Pareto optimality principle. A minimum Manhattan distance (MMD) approach to multiple criteria decision making in many-objective optimization problems is considered. This procedure is equivalent to the knee selection described by a divide and conquer approach that involves iterations of pairwise comparisons. Given such a directive, knee-based evolutionary algorithms have also been exploited to address dynamic optimization, constraint optimization, robust optimization and their applications including automatic design of the deep neural networks. This talk will reveal some of most recent progresses been made in these research areas in making evolutionary computation a step closer to become a commercial-off-the-shelf solution.
