In order to better solve the problem of distributed query optimization,a query optimization algorithm on gene expression programming(GEP)(QO-GEP)is presented.On the basis of QO-GEP,distributed GEP query optimization on grid service(DGEPQO-GS)is proposed which combines grid service.Simulated experiments show that with the increment of the number of query relation,query time which QO-GEP carries out query decreases apparently.Meanwhile,with the increase of the number of grid nodes,the average querying success rate of DGEPQO-GS increases significantly.
