andsoitis✦AI Summary
This article explains how the A* pathfinding algorithm can be applied to non-grid environments, such as navigating around circular obstacles. It details the mechanics of the algorithm, including the use of priority queues and heuristic estimates to find optimal paths.
The A* pathfinding algorithm is a powerful method for quickly generating optimal paths. Typically, people demonstrate A* navigating grid-based maps, but A* isn’t just a grid algorithm! It can work on any graph. We can use A* to find a path through this world of round obstacles.
