The traditional A* algorithm suffers from issues such as sharp turning points in the path, weak directional guidance during the search, and a large number of computed nodes. To address these problems, a modified approach called the Directional Search A*
this paper proposes a path planning method based on improved A* algorithm. Firstly, the heuristic function of the A* algorithm is weighted to improve the calculation efficiency. Secondly, in order to increase the practicality, the impact factors (road conditions) is introduced to the evaluation...
Finally, the IMOA-star outperforms the traditional A-star in terms of algorithm processing time, path smoothness, path length, and the number of random points. As a result, it should be considered a viable alternative to the traditional A-star for mobile robot path planning in a large ...
this paper based on the A-star algorithm uses the characteristics of jump point search to improve the node search mode and the search speed, and adds the angle evaluation cost function to the cost function of A-star algorithm to find the path with the least inflection point, so as to quic...
