Abstract

Two adaptive approaches applied in competitive differential evolution and in differential evolution with an ensemble of mutation strategies and parameter values are compared. The approach used in each of these two algorithms can be divided into two parts: adaptive mechanism and pool of strategies. Four variants of adaptation in differential evolution mutually combining these two parts of the two algorithms are experimentally compared in six benchmark functions at two levels of dimension. It was found out that the algorithms with the pool of competitive differential evolution are more reliable, whereas the variants using the pool of the other algorithm need mostly a smaller number of function evaluations to reach the stopping condition.
