conference paper description
This paper is aimed at the embedding and alternating of set of two discrete dissipative chaotic systems in the form of chaos pseudo random number generator for DE. This research deals with the initial investigations on the concept of a multi-chaos-driven evolutionary algorithm Differential Evolution (DE). This research represents the continuation of single-chaos-driven heuristics. It shows the performance dependency on the selection of chaotic systems as well as the moment of switching between these systems. Repeated simulations were performed on the selected set of test functions in higher dimensions. Finally, the obtained results are compared with canonical DE.
