The Model of Weights Optimization Based on Genetic Algorithm

The adjusting and optimizing of characteristics right is an important problem of the case amendment in CBR. And in practical applications, it is difficult to determine the vector of characteristics right of the case. Because of the global random search capability of genetic algorithm, in this paper a genetic algorithm to complete the direct search in space of right is presented, which is using genetic algorithm to optimize characteristics right by random adjusting Pc and Pm, the maximum fitness function can be found, so it can find a good right of the case. Experiments show that the method is reliable and effective.
