A* (pronounced "A-star") is a graph traversal and path search algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. Given a weighted graph, a source node and a goal node, the algorithm finds the shortest path (with respect to the given weights) from source to goal. One major practical drawback is its space complexity, as it stores all generated nodes in memor…

May 30, 2022 · Pathfinding is a common programming challenge with a wide range of uses. We know it mainly from navigation and games. However, once you know the core algorithms, you'll find that they apply to more abstract optimization and sequencing problems. In this tutorial, we'll look at a basic pathfinding algorithm, based on Dijkstra's algorithm.
