Lu Jinshi Li Hongxing(Dept.of Inf.Eng.,Dalian Inst.of Light Ind.,Dalian 116034) Li Xiao(Xinjiang Institute of Physics,CAS,Wulumuqi 830011)  
To distributed heterogeneous database,query optimization is not only the very complicated question but also the key factor about systemic capability.In this paper,a genetic algorithm based on position and value tree structure encoding is used at problem of query optimization.Its effect is very good.
