WebMar 24, 2024 · A Hamiltonian cycle, also called a Hamiltonian circuit, Hamilton cycle, or Hamilton circuit, is a graph cycle (i.e., closed loop) through a graph that visits each node exactly once (Skiena 1990, p. 196). A graph possessing a Hamiltonian cycle is said to be a Hamiltonian graph. WebMay 17, 2016 · Treat the graph as undirected, do the algorithm do check for bipartiteness. If it is bipartite, you are done, as no odd-length cycle exists. Otherwise, you will find an odd-length undirected cycle when you find two neighbouring nodes of the same color. Track back to the way you came until that node, these are your nodes in the undirected cycle.

WebJul 9, 2024 · In the end, path [i] [i] is the length the shortest cycle going through i. Consequently, you need to find min (path [i] [i]) for all i. And if you want cycle itself (not only its length), you can do it just like it's usually done with normal paths: by memorizing k during execution of algorithm.
