Abstract

Based on the clonal selection theory, the main mechanisms of clone are analyzed in this paper, a new immune operator, Clonal Operator, inspired by the Immune System is discussed firstly. Based on the Clonal operator, we propose Immune Clonal Strategy Algorithm (ICSA); three different mutation mechanisms including Gaussian mutation, Cauthy mutation and Mean mutation are used in IMSA. IMSA based on these three methods are compared with Classical Evolutionary Strategy (CES) on a set of benchmark functions, the numerical results show that ICSA is capable of avoiding prematurity, increasing the converging speed and keeping the variety of solution. Additionally, we present a general evaluation of the complexity of ICSA.
