Everyone is strong enough to share their support. Topic: _Given a directed graph G=(V,E).Set P to be a set of G's simple paths with disjoint vertices.If each vertex in V happens to be on a path of P, P is said to be a path coverage of G.A path in P can start from any vertex of V and have an arbitrary length, especially 0.The minimum path cov ...

An algorithm for searching all paths between two points based on a graph's contiguity list implementation

The algorithm is implemented in C++. Why write this algorithm? Because it is so hard to find only the implementation of the adjacency matrix on the network, I have made an implementation of the adjacency chain table myself, which can increase the speed. This is achieved by using one of three stacks to traverse all vertices, the second stack t ...
