WebDec 7, 2024 · I'm trying to apply it to finding the shortest Ham Path, but this does not seem so obvious, since the DFS search does not find ALL Ham Paths (even with multiple starts from all nodes) . For example, suppose that during DFS I have found a (partial) path (0) - … The problems of finding a Hamiltonian path and a Hamiltonian cycle can be related as follows: • In one direction, the Hamiltonian path problem for graph G can be related to the Hamiltonian cycle problem in a graph H obtained from G by adding a new universal vertex x, connecting x to all vertices of G. Thus, finding a Hamiltonian path cannot be significantly slower (in the worst case, as a function of the number of vertices) than finding a Hamiltonian cycle. old street comedy clubWebOct 25, 2024 · Approach: The given problem can be solved by using Backtracking to generate all possible Hamiltonian Cycles.
