Abstract:

The influence of knowledge on the evolution process in traditional cultural algorithms is unified. Evolving to the same direction may lead to premature convergence. A new knowledge named dual knowledge determined by situational knowledge, normative knowledge and the current individual is proposed. When dual knowledge conducts individual evolution, the direction of different individual is decided by the individual dual knowledge. Simulation of complicated functions is performed. The results indicate that this algorithm has abilities of global convergence and good performance in solving highdimensional optimization problems.

Key words: dual knowledge, cultural algorithm, influence strategy
