Find largest cycle in graph
WebMay 1, 2024 · Note that for any strongly connected graph, the longest path always contains all the nodes in the graph. Using observation 2, replace all strongly connected components with a "Super node" and add the size of the SCC to the answer while doing so. The graph obtained now is a DAG. Using observation 1, find the longest path length for this DAG … WebReturns a cycle found via depth-first traversal. The cycle is a list of edges indicating the cyclic path. Orientation of directed edges is controlled by orientation. Parameters: …

WebFeb 11, 2011 · Given a graph for which we need to check if there exists a Hamiltonian Cycle or not, assign weight 1 to each edge. Now run your algorithm to get the maximum weight cycle. If the weight is < n, then the original graph has no Hamiltonian cycle, otherwise it does.
