Dijkstra's example

WebJan 10, 2024 · Dijkstra's algorithm is an algorithm that is used to solve the shortest distance problem. That is, we use it to find the shortest distance between two vertices on a graph. WebFeb 20, 2024 · A* is like Dijkstra’s Algorithm in that it can be used to find a shortest path. A* is like Greedy Best-First-Search in that it can use a heuristic to guide itself. In the simple case, it is as fast as Greedy Best-First-Search: In the example with a concave obstacle, A* finds a path as good as what Dijkstra’s Algorithm found:
