Course Introduction:A* algorithm: a powerful tool for efficient path search Algorithm A is a powerful path search algorithm in computer science, which is widely used in game development, robot navigation and other fields. It efficiently finds the shortest path from the start point to the end point by combining the advantages of heuristic search and Dijkstra algorithm. This article will explore in-depth the core concepts, Python implementation, application scenarios, and advantages and disadvantages of the A algorithm. The core idea of ??A* algorithm The A algorithm cleverly combines the advantages of Dijkstra algorithm (finding the shortest path to all nodes) and greedy best-first search (selecting the closest node to the target based on heuristic functions). Imagine finding the shortest route between two cities on a map: Dijkstra Algorithm to explore
