differential evolution; current-to-pbest mutation; strategy competition; CEC 2013 test suite

New variants of the adaptive competitive differential evolution algorithm are proposed and tested experimentally on the CEC 2013 test suite. In the new variants, the adaptation is based on the competition of several strategies. The current-to-pbest mutation borrowed from JADE is included into the pool of the competing strategies in newly proposed variants. The aim of the experimental comparison is to find whether the presence of the current-to-pbest mutation strategy increases the efficiency of the differential evolution algorithm, especially on rotated objective functions. The results of the experiments show that the new variants performed better in a few of the test problems, while the benefit is not observed in the majority of the test problems.
