Abstract: In order to solve the numerical optimization problem, the estimation of distribution algorithm based on normal distribution is researched and improved. On the basis of the existing algorithms, the replacement strategy with advantages, competing mechanism and pattern search are introduced. Compared with five kinds of improved algorithms, it is proved that the proposed strategies and the modified algorithms are effective and can find even better solutions. Finally, the effects of improvement are explained based on the numerical simulations and statistical analysis.

Key words: estimation of distribution algorithm (EDA), swarm intelligence, normal distribution, pattern search
