Dijkstra's algorithm code

WebFeb 29, 2024 · 4. I have implemented Dijkstra's algorithm in C++, but it seems a bit complicated since I really tried to follow the process of the algorithm as much as I could. If there's any simplification you would suggest, I would really appreciate, because this task was only for me to get familiarized with this method before the A* algorithm. WebOne algorithm for finding the shortest path from a starting node to a target node in a weighted graph is Dijkstra’s algorithm. The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph.
