WebAlgorithm. There will be two core classes, we are going to use for Dijkstra algorithm. Vertex: This class contains name, visited flag, predecessor (To track the short path, so that we can backtrack) and distance from source node and also the list of outgoing edge from this vertex. Edge: This class contains Source vertex, target vertex, and weight. WebOct 4, 2024 · The single-source shortest path issue for a directed graph G = (V, E) with non-negative edge weights is solved by the greedy algorithm known as the Dijkstra algorithm, which bears the name of its discoverer, Dutch computer scientist Edsger Dijkstra. In other words, we suppose that for any edge (u, v) є E, w (u, v) ≥ 0.
