%X The information is stored at the data warehouse in form of views.According to cost,some views are selected to answer queries in the data warehouse.The cost model of view materialization was presented.The solution and strategy using genetic algorithm and improved algorithm were given.Finally,experimental results show that the proposed algorithms can deliver a similarly most optimal solution.
