Motivation To approximate the shortest path in real-life situations, like- in maps, games where there can be many hindrances. We can consider a 2D Grid having several obstacles and we start from a sou...

If you’re a game developer, you might have always wanted to implement A* as character (or enemy) pathfinding. I know a couple of years ago I did, but with my level of programming at the time I had iss...

Given a graph and a source vertex in the graph, find shortest paths from source to all vertices in the given graph. Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree. ...

Movement for a single object seems easy. Pathfinding is complex. Why bother with pathfinding? Consider the following situation: The unit is initially at the bottom of the map and wants to get to the...
