In computer science, A* (pronounced as "A star"( listen)) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting an efficiently traversable path between multiple points, called nodes. Noted for its performance and accuracy, it enjoys widespread use. However, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance,
although other work has found A* to be superior to other approaches.
In 1968, AI researcher Nils Nilsson was trying to improve the path planning done by Shakey the Robot, a prototype robot that could navigate through a room containing obstacles. This path-finding algorithm, that Nilsson called A1, was a faster version of the then best known method, Dijkstra's algorithm, for finding shortest paths in graphs. Bertram Raphael suggested some significant improvements upon this algorithm, calling the revised version A2. Then Peter E. Hart introduced an argument that established A2, with only minor changes, to be the best possible algorithm for finding shortest paths. Hart, Nilsson and Raphael then jointly developed a proof that the revised A2 algorithm was optimal for finding shortest paths under certain well-defined conditions.
Improving on Dijkstra, A* takes into account the direction of your goal. Dr Mike Pound explains.
Correction: At 8min 38secs 'D' should, of course, be 14 not 12. This does not change the result.

A * ALGORITHM IN ARTIFICIAL INTELLIGENCE WITH EXAMPLE
This video will clear all your doubts regarding A * algorithm in Artificial Intelligence with examples.
This A* Path Finding tutorial will show you how to implement the a* search algorithm using python. We will be building a path finding visualizer tool to visualize the a star pathfinding algorithm as it runs. This astar pathfinding algorithm is an informed search algorithm which means it is much more efficient that your standard algorithms like breadth first search or depth first search.

Welcome to the first part in a series teaching pathfinding for video games. In this episode we take a look at the A* algorithm and how it works.
Some great A* learning resources:

This A* Path Finding tutorial will show you how to implement the a* search algorithm using python. We will be building a path finding visualizer tool to visualize the a star pathfinding algorithm as it runs. This astar pathfinding algorithm is an informed search algorithm which means it is much more efficient that your standard algorithms like breadth first search or depth first search.

#python #pathfinding #astar
In computer science, A* (pronounced as "A star"( listen)) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting an efficiently traversable path between multiple points, called nodes. Noted for its performance and accuracy, it enjoys widespread use. However, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance,
although other work has found A* to be superior to other approaches.
In 1968, AI researcher Nils Nilsson was trying to improve the path planning done by Shakey the Robot, a prototype robot that could navigate through a room containing obstacles. This path-finding algorithm, that Nilsson called A1, was a faster version of the then best known method, Dijkstra's algorithm, for finding shortest paths in graphs. Bertram Raphael suggested some significant improvements upon this algorithm, calling the revised version A2. Then Peter E. Hart introduced an argument that established A2, with only minor changes, to be the best possible algorithm for finding shortest paths. Hart, Nilsson and Raphael then jointly developed a proof that the revised A2 algorithm was optimal for finding shortest paths under certain well-defined conditions.
