Differential Evolution variants combined in a Hybrid Dynamic Island Model

Several Variants of the Differential Evolution (DE) algorithm have been among the winners of competitions on bound constrained optimization problems in distinct editions of the Congress on Evolutionary Computation (CEC). This paper compares some of those variants presented in the last five years. Those algorithms are also combined in two adaptive dynamic Island Models (IM), which adjust the topology according to the algorithms applied in their islands. The Island Models are able to adaptively direct more solutions to the islands with more qualified algorithms to solve the problem. The results allow to verify whether the combination of the recently proposed DE variants in an adaptive dynamic structure is better than using each one individually.
