Abstract EN
A fixed evolutionary mechanism is usually adopted in the multiobjective evolutionary algorithms and their operators are static during the evolutionary process, which causes the algorithm not to fully exploit the search space and is easy to trap in local optima.
In this paper, a SPEA2 algorithm which is based on adaptive selection evolution operators (AOSPEA) is proposed.
The proposed algorithm can adaptively select simulated binary crossover, polynomial mutation, and differential evolution operator during the evolutionary process according to their contribution to the external archive.
Meanwhile, the convergence performance of the proposed algorithm is analyzed with Markov chain.
Simulation results on the standard benchmark functions reveal that the performance of the proposed algorithm outperforms the other classical multiobjective evolutionary algorithms.
