A Hamiltonian path is a simple path that contains all vertices in the graph. Show that any complete graph with 3 or more vertices has a Hamiltonian path. How many Hamiltonian paths does a complete graph with n vertices has? Justify your answer.

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.
