Dijkstra's shortest path algorithm c++
WebFeb 12, 2024 · 1. Dykstra's is normally implemented with a priority queue, and even though the c++ std::priority_queue does not allow element modification, it is easy to "keep pushing" and discard stale entries on pop. You should research this approach as it is quite canonical I think. Oliver Schönrock. Feb 16, 2024 at 22:10. 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.
