C Program to Check Whether Graph is DAG - A directed acyclic graph (DAG) is a graph that is directed and without cycles connecting the other edges. The edges of this graph go one way. This is a C++ program to check whether the graph is DAG.AlgorithmBegin
然而第一名的算法十分简单: 对每个点依次 BFS 计算它到各点的距离和, BFS 中顺便估一个距离和的下界, 下界超过当前已知的 top-k 的 bound 就剪枝. 由于实现技巧太好, 他们的程序快我们好几倍. 其中主要是由于他们的 BFS 是用 bitset 及位运算并行做的, 另外还要归功于内存分配的策略. 他们在读完数据后,...
