Abstract

We propose an informative Differential Evolution (DE) algorithm where the information gained by the individuals of a cluster will be exchanged after a certain number of iterations called refreshing gap. The DE is empowered with a clustering technique to improve its efficiency over multimodal landscapes. During evolution, self-adaptive behaviour helps in re-clustering. With the better explorative power of the proposed algorithm we have used a new local search technique for fine tuning near a suspected optimal position. The performance of the proposed algorithm is evaluated over 25 benchmark functions and compared with existing algorithms.
