In this paper, a self-adaptive two phase approachfor large scale optimization is proposed. In the first phase, wedesign a uniform discrete search method which can quicklyand roughly scan the search space and find good initial points.Then we continuously narrow the search space and makemore precise search in a dynamically self-adaptive way. In thesecond phase, we design a dynamically self-adaptive groupingsearch scheme which can group the variables into severalgroups dynamically and assign different function evaluationsto different variable groups self-adaptively during each groupsearch. The experiment results indicate the proposed algorithmis effective and efficient.
