摘要
对自适应演化算法进行了改进,修改了变异操作中分量值会超出定义域范围的错误,改善了重组操作并不一定产生更优后代的缺点,从而大大提高了收敛到全局最优解的概率。通过将此两种算法引入微波电路的设计中,通过结果对照,证明了改进算法的优良特性。
The adaptive evolvement arithmetic is introduced first, then the improved arithmetic is proposed which solves the problem that the offspring will overrun the defining region in the mutation operation, and overcomes the defect that reforming operation does not always generate advanced offspring, thus greatly increasing the probability of converging to a globally optimal solution. The improved arithmetic is introduced into the optimal design of microwave circuit. A comparison with the unmodified arithmetic shows that the improved arithmetic has better performance.
