- Abstract:
-
In this paper, a multi-target point path planning algorithm is proposed based on discrete brainstorm optimization (DBSO) to guarantee that a mobile robot can traverse multiple target points with the shortest path. First, considering the influence of obstacles on path planning, the shortest obstacle avoidance distance between target points is used as the judgment basis to improve rationality of the planned path. Secondly, the traditional discrete brainstorming algorithm will fall into local optimum in advance when solving combinatorial optimization problems. Therefore, a heuristic adaptive path optimization strategy is proposed. It increases path diversity and improves convergence speed of the algorithm by designing a fitness selection function related to the number of iterations and improving the heuristic crossover operator. A map model is established based on the grid method, and multiple targets are selected in different environmental maps for comparison and simulation to verify effectiveness of the proposed algorithm and its adaptability to different environments.
