Abstract:

Cooperative coevolution algorithm is a hot research topic in computational intelligence in recent years.Inspired by the principle of natural selection,cooperative coevolution algorithm constructs two or more groups and establishes the cooperative relationship among the groups.Two or more groups cooperates together to improve their performance,be adapted to dynamic evolutionary circumstance of complicated systems and largescale evolutionary circumstance,thus achieving the goal of population optimization.The research state and advances of cooperative coevolution algorithms in domestic and foreign are discussed and surveyed.The paper introduces the three main aspects of cooperative coevolution algorithm: basic structure and corresponding studies,basic and improved algorithms,and some applications in the real life.Finally,research prospects are indicated.

Key words: cooperative coevolution algorithm;problem decomposition;subspace correlation
