How dijkstra algorithm works

WebApr 6, 2024 · Dijkstra’s algorithm works on directed graphs, where nodes are connected with weighted non-negative edges. The algorithm finds the distance from a single source node to all other nodes in the graph. If we only care about the shortest distance to a single target node, we can simply stop the algorithm after that particular path has been found. ... WebFeb 20, 2024 · Instead of selecting the vertex closest to the starting point, it selects the vertex closest to the goal. Greedy Best-First-Search is not guaranteed to find a shortest …
