The lower bounds of signed domination number have been studied in [ 5 ] . in this paper we do further research and obtain some new lower bounds of signed domination number of a graph represented by the new parameter 5 * 本文主要对于符号控制数的下界和连通图的强控制数的上界以及全控制数和连通控制数的nordhaus - graddum型界的问题进行了研究。
And about the symbols , after analyzed the structural properties of alphabetic and digital characters on vehicle license plate in detail , the dissertation selects features of minutiae , closed curve and corners in strokes as the foundation of character recognition to recognize characters in license plate 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。 ”
