今天,幫別人做了個最佳化問題問題是一個“分布函數的變上限積分的最大值問題”,還涉及到了分布函數的逆,“Inverse of the normal cumulative distribution function”可能是我遇到過的比較難算的東西。求解思想;1.積分可分解化為求和SUM, 間距劃的越小計算時間越長,間距過大精確度降低....2.變上限積分同上,但間距要統一,不能因上限改變,間距改變,解決方案:function

"兩層規劃(Bi-level Programming)是一類具有主從遞階關係結構的數學模型,它是將最佳化問題作為約束條件的極值問題。當前對線性兩層規劃的研究比較完善,而對非線性兩層規劃的研究仍比較少。已有文獻證明,非線性兩層規劃屬於一類強 NP-hard問題,解決起來相當複雜,尤其是當涉及變數個數比較多時,求解其全域最優解更為困難。當前國內外相關研究中,比較有代表性的幾份文獻有:# J. F. Bard和J. T. Moore等研究提出了求解該類問題的分支定界演算法;#
