The invention discloses a coarse-grain parallel algorithm based on an ant colony optimization and genetic algorithm. An initial city of m ants is initialized; ant colony traveling is carried out for one time, and traveling results are used as the initial population of GA; ant colony traveling is carried out for one time, and ants with the shortest route in the traveling are computed and recorded; the selection operator, the hybridization operator and the mutation operator of the GA operate; and if an iteration process accords with a preset iteration condition, operation time is computed and output, and the optimal solution is output. Massive calculation shows that the computing speed of the parallel algorithm is better than that of an equal serial algorithm.
