%X Ant Colony System (ACS) method was adopted to solve the problem of materialized view selection under a storage space constraint. The pheromone was updated locally and globally, and the optimization solution of each iteration was locally searched, and finally a reasonable solution was got. Compared with genetic algorithm, the simulation results of ACS show its superiority.
