Abstract

Multi-population methods are important tools to solve dynamic optimization problems. However, to effectively track multiple optima, algorithm designers need to address a key issue: adaptation of the number of populations. In this paper, an adaptive multi-population framework is proposed to address this issue. A database is designed to collect heuristic information of algorithm behavior changes. The number of populations is adaptively adjusted according to statistic information related to the current evolving status in the database as well as a heuristic value. Several other techniques are also introduced, including a heuristic clustering method, a probabilistic prediction scheme, a population hibernation rule, and a peak hiding method. The particle swarm optimization and differential evolution algorithms are implemented into the framework, respectively. A set of multipopulation based algorithms are chosen to compare with the proposed algorithms on the moving peaks benchmark using four different performance measures. The proposed algorithms are also compared with two peer algorithms on a set of multi-modal problems in static environments. Experimental results show that the proposed algorithms outperform the other algorithms in most scenarios.
