Application of Improved Dijkstra Algorithm in Two-dimensional Path Planning Problem

The Dijkstra algorithm is a typical single-source shortest path algorithm for calculating the shortest path from one node to the other in a non-negative weight map, but its use of the roulette method greatly affects the node selection. Speed and efficiency. Therefore, on the basis of ensuring the search accuracy, this paper improves the initial Dijkstra algorithm to improve the efficiency of the algorithm and meet its needs in 2D or 3D path planning. In this paper, MATLAB2018a is used as the experimental platform to simulate the initial Dijkstra algorithm and the improved Dijkstra algorithm. The experimental results show that the improved algorithm greatly reduces the path planning vision and improves the operating efficiency.
