Combined nested partitions algorithm based on ordinal optimization

The main ideas of nested partitions (NP) method were introduced, its efficiency was theoretically analyzed and a way was proposed to improve the optimization efficiency of the algorithm. Then the ordinal optimization (OO) algorithm was introduced and the ideas of OO were incorporated into the determining of feasible region and the estimating of the promising index. The combined OONP algorithm was analyzed that drew on the two optimization methods. The OONP algorithm adopted the exponential convergence rate ability of OO algorithm and NP algorithm, so that it improved the efficiency and feasibility. Simulation results demonstrate the OONP algorithm.
