摘 要:介绍了图像关联规则的相关概念,描述了传统的双种群遗传算法的执行过程;针对采用固定染色体交叉概率和染色体变异概率容易出现早熟、收敛速度较慢等问题,设计出了能自适应调整的染色体交叉算子和变异算子。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作,是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等),但是不管是采用何种交叉操作,新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的,采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性,因此照此下去就会出现早期收敛现象,使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。
