而对于符号，通过对车辆牌照上英文字符和数字字符结构特征的详细分析，选择字符中的细节点特征、闭合曲线特征和拐角点特征作为字符识别的依据，根据这些特征来识别牌照上的英文字母和数字字符。 - Through chaos optimization method embedded into the genetic algorithm . the algorithm with the combination the advantages of the genetic algorithm and chaos optimization method which need not the optimal problem function ' s differential and promote the ability of the genetic algorithm ' s locally meticulous search can be obtained with the faster convergence and the greater probability for the global solution . a chaotic sequence is inserted into the search procedure of genetic algorithm , which can overcome premature of the search by genetic algorithm and the speed of convergence is faster than standard genetic algorithm
对遗传算法进行了理论分析，并且研究了遗传算法的设计与实现；利用混沌优化方法不依赖于梯度信息的性质，将其与遗传算法相结合，提出了一种求解连续不可微函数优化问题的混合遗传算法；基于对于符号动力系统的研究，利用混沌序列的遍历性，将混沌序列引入遗传算法中，提出一种嵌入哈尔滨工程大学博土学位论文一混饨序列的遗传算法，该算法有效地克服了标准遗传算法中的早熟现象，并且具有更快的收敛速度。 ”
