Study and analysis of three basic path planning algorithms

With the popularization of navigation systems in mobile applications, path planning, as the most important part of navigation, is receiving more attention. The planned path is generated by the corresponding algorithm. There are many algorithms for implementing path planning, and the principles and application scenarios of each algorithm are not entirely the same. The three most common algorithms are Dijkstra’s Algorithm, A * Algorithm, and D * Algorithm. In this article, the author mainly summarizes the introduction and basic workflow of the above three algorithms, and infers and analyzes the application scenarios and conditions of the above three basic algorithm models. Through the organized content, the author analyzes the above three algorithms and concludes that Dijkstra’s Algorithm is suitable for beginners to learn and perform path planning in simple static environments, The A * algorithm is suitable for path planning in ordinary static environments with relatively small maps, while in ordinary dynamic environments, the D * algorithm is more suitable.
