The A* Algorithm is a popular pathfinding and graph traversal method used in computer science and artificial intelligence. It efficiently finds the shortest path from a starting point to a target by combining features of both Dijkstra's Algorithm and Greedy Best-First Search. It uses a heuristic to estimate the cost from the current node to the goal, allowing it to prioritize paths that seem more promising. The algorithm maintains a priority queue of nodes to explore, calculating a score for each node based on the total cost from the start and the estimated cost to the goal. This approach helps it navigate complex environments effectively, making it widely used in applications like video games and robotics.
