Using genetic algorithm for path planning

ased on massively parallel connectionist network, to find the collision free paths,the algorithm was developed. Because of the local minimum value in this algorithm,the collision free path perhaps is not the shortest. To avoid local minimum value, the simulated annealing and some heuristic methods are used, however these methods can only ensure the collision free path, the global shortest path is not sure to be finded, so the genetic algorithm is introduced into the algorithm for its efficiency on optimization. Because of the specific property of the real question, the genetic algorithm used in this paper is different from the general genetic algorithm in some aspects. For example, in this algorithm, the problem is in continuous planning space, the coded string for the path is difficult to generate, so the path points are directly used as genetic units, and the idea "distant relatives can pair" to create next generation is used to improve the efficiency of the algorithm. The simulation shows good results.
