Multi-modal optimization refers to locating not only one optimum but a set of locally optimal solutions. Niching is an important technique to solve multi-modal optimization problems. The ability of discover and maintain multiple niches is the key capability of these algorithms. In this paper, differential evolution with an ensemble of restricted tournament selection (ERTS-DE) algorithm is introduced...
This paper proposes a new chaotic hybrid cultural algorithm to solve constrained optimization problems. In the proposed method, differential evolution is embedded into cultural algorithm as its population space and applies situational and normative knowledge sources in belief space to influence the variation operator of differential evolution. We apply chaos theory to obtain self-adaptive parameter...
