Abstract: When the genetic algorithms are applied to solve travelling salesman problems, they are often faced with the problems of early convergence and being trapped in a local optimum. On the basis of co-evolution strategy, this paper proposes an improved genetic algorithm, which dynamically adjusts its fitness function and the probabilities of evolution operator in order to reduce the possible individual inbreeding degradation, and then effectively controls the evolutionary process. Compared with typical genetic algorithms, this improved algorithm can improve the speed of convergence and obtains better performance. Finally, this algorithm is verified on the TSP problem in 144 cities in China. The simulation results show that the improved genetic algorithm has better global searching performance and uses less convergence time.
