WebDefinitions. A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph, each edge has an orientation, from one vertex to another vertex.A path in a directed graph is a sequence of edges having the property that the ending vertex of … WebJan 25, 2024 · k is the number of paths to find. Using your programming language's form of infinity for d and k will give you all paths§. § obviously if you are using a directed graph and you want all undirected paths between s and t you will have to run this both ways: find_paths [s, t, d, k] find_paths [t, s, d, k]
