WebApr 12, 2024 · For simplicity and generality, shortest path algorithms typically operate on some input graph, G G. This graph is made up of a set of vertices, V V, and edges, E E, that connect them. If the edges have weights, the graph is called a weighted graph. Sometimes these edges are bidirectional and the graph is called undirected. WebAug 27, 2024 · The shortest path from one vertex to another vertex is a path in the graph such that the sum of the weights of the edges that should be travelled is minimum.
