中文摘要 | 本文基於傳統單純形法提出一改良式單純形法,試改善傳統單純形法低計算效率與參數多的問題。依此,進而以族群搜尋策略與二段式處理方式,探討對多極值與非凸區域最佳化問題找尋其全域最佳解之特性,文中以幾個實例測試。 |
英文摘要 | In this paper, a modified simplex search method based on the conventional simplex method is proposed. First, the search algorithm of the conventional simplex method is modified to find out the local extreme value for optimization problems to meet a satisfactory computational efficiency. Next, the population searching strategy is introduced in the first phase of the modified search algorithm. The best design point obtained from the final design results in the first phase is selected as the initial design point in the second phase of the modified search algorithm. The proposed modified simplex search method can find the global optimum for multi-modal and non-convex problems, and has been validated by some examples. |
