Abstract: In general, optimization is important task. optimization of a query is a difficult task when the case of large database it a more difficult to solve the problem and that can be said as NP-hard problem. This research is done to find a suitable query optimization algorithm on the basis of various factors like cost and time. In this research paper, various optimization algorithm is used to find the optimized result of the NP-hard problem.
Keywords: Ant colony algorithm, distributed database, QUERY execution plan, search strategies, NP-hard problem
