Abstract: This paper applies the Ant Colony Algorithm(ACA) to the optimization of multi-join. It introduces basic principles and working process of ACA, then builds a multi-join query optimization model based on ACA. With the method proposed by this paper, a high quality solution to the multi-join queries problems can be obtained.

Key words: Ant Colony Algorithm(ACA), optimization, multi-join query
