Penalty function is introduced in the adaptive value function to speed up the convergence of the algorithm and ensure that the assignment reduction includes fewer attributes with stronger support 在交叉规则中，采用了单点交叉，最大迭代代数被作为停止准则，算法获得较佳的搜索效果。

An improved ga that is named head - and - tail alternate crossover ga is proposed to overcome the shortcoming of conventional single - point crossover ga on the optimizing of multi - parameter system 针对传统单点交叉遗传算法在处理多参数优化问题时存在的不足，提出了首尾轮换交叉遗传算法。
3.
The basic idea of the algorithm is that the bits of binary string behind the crossover point are crossed if the generation number is odd and the bits in the front of crossover point are crossed if the generation number is even 该算法的基本思想是：当遗传代数为奇数时，采用尾部单点交叉；当遗传代数为偶数时，采用头部单点交叉。
