How to check the graph for the uniqueness property of the path?

Hi, everyone

Some directed graph is given. Check the graph for the uniqueness property of the path(for any two vertices v u, there is no more than one simple path with the beginning in u and the end in v). Simple path is a non-empty path whose vertices are all pairwise distinct.

Does anyone know a solution to this problem faster than running BFS from each vertex?
