- Abstract:
-
An improved genetic algorithm is proposed to address the limitations of conventional genetic algorithms in path planning, such as excessive turning angles, redundant turns, and susceptibility to local optima. First, an upgraded population initialization strategy is proposed. This method selects a transitional point to generate a route from the starting point to the transition point and another from the transition point to the endpoint. The segments are then combined to establish a complete route, thereby forming a high-quality initial population and improving early search efficiency. Second, an enhanced tournament selection approach is utilized, which integrates simulated annealing with region-based population segmentation to increase population diversity and mitigate local optima entrapment. Finally, the Q-learning algorithm is incorporated into crossover and mutation operations, enabling the algorithm to interact with the environment, continuously learn, and optimize its action selection strategy. This integration enhances the algorithm’s global search capabilities, leading to the development of superior populations. As demonstrated by path planning simulations, the proposed enhanced genetic algorithm has the capacity to reduce path length and turning angles, decrease the number of turns, and ultimately identify more optimal pathways when compared to traditional genetic algorithms, enhanced adaptive genetic algorithms, and improved catastrophe genetic algorithms.
