代码说明:

python的正则表达式常用的几个点,包含:1导入,2:元字符之类,内容预览:元字符# d 匹配任何十进制数;相当于[0-9]# D 匹配任何非数字字符;相当于[^0-9]# s 匹配任何空白字符;相当于[ fv]# S 匹配任何非空白字符;相当于[^ fv]# w 匹配任何字母数字字符;相当于[a-zA-Z0-9_]# W 匹配任何非字母数字字符;相当于[^a-zA-Z0-9_]#  匹配一个单词边界,指单词和空格间的位置

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • GA-DF2
    说明:  利用GA遗传算法解决欺骗函数最优问题,具体问题描述如下,如有问题请与我联系(The deceptive functions are a family of functions in which there exists low-order building blocks that do not combine to form the higher-order building blocks. Here, a deceptive problem that consists of 25 copies of the order-4 fully deceptive function DF2 is constructed for this paper. DF2 can be described as follows: f(0000)=28 f(0001)=26 f(0010)=24 f(0011)=18 f(0100)=22 f(0101)=6 f(0110)=14 f(0111)=0 f(1000)=20 f(1001)=12 f(1010)=10 f(1011)=2 f(1100)=8 f(1101)=4 f(1110)=6 f(1111)=30 This problem has a maximal function value of 750.)
