Webb16 nov. 2024 · Shortest paths are normally simple. Our algorithms ignore zero-weight edges that form cycles, so that the shortest paths they find have no cycles. Shortest paths are not necessarily unique. There may be multiple paths of the lowest weight from one vertex to another; we are content to find any one of them.

Webb10 apr. 2024 · $\begingroup$ It is #P-complete on general directed graphs, not on DAGs. On DAGs, "path" and "simple path" are the same concept. The dynamic programming algorithm puts this problem in P. The longest s-t path in a DAG is at most the depth of the DAG which is at most the number of vertices. $\endgroup$ – WebbFor a simple graph, a path is equivalent to a trail and is completely specified by an ordered sequence of vertices. For a simple graph , a Hamiltonian path is a path that includes all vertices of (and whose endpoints are not adjacent).
