Nov 7, 2024 · A guide to understanding and implementing the A* search algorithm in Python. See how to create efficient solutions for complex search problems with practical code examples. Learn optimization strategies used in production environments.

Compared to Dijkstra's algorithm, the A* algorithm only finds the shortest path from a specified source to a specified goal, and not the shortest-path tree from a specified source to all possible goals. This is a necessary trade-off for using a specific-goal-directed heuristic.

At its core, A* is a best-first search algorithm that evaluates paths using two components: g (n): The actual cost from the start node to node n. h (n): A heuristic estimate of the cost from node n to the goal. f (n) = g (n) + h (n): The total estimated cost of reaching the goal via n.

Apr 14, 2025 · A* Search Algorithm is a simple and efficient search algorithm that can be used to find the optimal path between two nodes in a graph. It will be used for the shortest path finding. It is an extension of Dijkstra’s shortest path algorithm (Dijkstra’s Algorithm).
