Abstract  

To improve the weak spatial exploration ability and the poor diversity of individual distribution of offspring in current bean optimization algorithm, a bean optimization algorithm based on Cauchy distribution and parent rotation mechanism(BOA-CPR) is presented. Firstly, a population distribution model based on Cauchy distribution is constructed and used in the exploration phase to improve the global search ability of the algorithm. Then, a parent rotation mechanism based on the roulette wheel selection is established to enhance the diversity of offspring. Finally, an adaptive adjustment mechanism for three important parameters, including individual distance threshold, distribution variance and descendant ratio, is designed to improve the dynamic optimization ability of the algorithm for complex optimization problems. Experiments show that BOA-CPR ranks better in average fitness value and Friedman detection index.
