题 题意 给你代表0到n-1的n个点,然后这n个点有d个相连点,相连点的XOR sum 为s,求所有的边。 分析 知识:a^b^a=b,a^b^b=a. 把相连点为1的i存进队列,i的唯一相连点就是S。 然后得到一条边i到s,对i的相连点S,d--,s^=i,就相当于去掉i这个点。 然后再判断S的相

方法1:两遍最大流。一遍最大流后,把满流边容量+1,非满流边改为INF;再求最小割即为答案。我大概想了下证明:能构成最小割的边在第一次跑最大流时都满流,然后按那样改变边容量再求一次最小割,就相当于再在那些 满流可能是属于最小割的边 中挑出最少的边形成ST割。 1 #include 2 #incl.....
