WebIn graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph. A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges. WebIn a graph, a path is a sequence of nodes in which each node is connected by an edge to the next. The path length corresponds to the number of edges in the path. For …
