| Abstract: | In this paper, an adaptive genetic algorithm is proposed to solve the problem of choosing the probabilities of crossover and mutation. A special function is defined to adptively adjust the above two parameters, which garantees the diversity and stability of genetic algorithm and avoids its premature convergence. Application examples of diagnostic knowlege acquisition de-mostrate that the proposed approach is more effective than standard genetic algorithm. |
