differential evolution, adaptation, experimental comparison

The differential evolution algorithm using competitive adaptation was compared experimentally with the state-of-the-art adaptive versions of differential evolution on CEC2005 benchmark functions. The results of experiments show that the performance of the algorithm with competitive adaptation is comparable with the state-of-the-art algorithms, outperformed only by CoDE and JADE algorithms in this test. A modification of competitive differential evolution preferring successful strategy for a longer period of search was also investigated. Such modification brings no improvement and the standard setting of the competition recommended in previous papers is suitable for applications.
