查询词典 optimization

The character of this new method is that the mechanism of the GA is not changed but the search space and the coefficient of the adjustment of th e optimization parameter are reduced continually, which leads to generation evolution to the next generation in order to produce better optimization indivi duals so as to improve the performance of the GA and get over the disadvantage o f the GA.
