Mingxi Luo · 2025
This paper presents a dual-optimization learning model combining genetic algorithms for global path planning with local obstacle avoidance algorithms for robot navigation in dynamic environments. The model integrates$A^{*}$for global path planning, and the Dynamic Window Approach (DWA), fuzzy control, and Q-learning for real-time obstacle avoidance. An improved multi-objective genetic algorithm is used to optimize path length, safety, and smoothness. Experimental results demonstrate that the GAA-DFQ algorithm outperforms traditional$\mathrm{A}^{*}$and GAA in path planning, showing the lowest collision rate (2.5 %), the shortest path length (181 units), and the fastest computation time (85 seconds), proving its efficiency and stability in complex environments.
