In this paper , a concept of strictly efficient solution of the optimization problem for a set - valued mapping is introduced . it is proved that strictly efficient point set of the objective space is connected when objective function is cone convex - like , and that if objective function is cone convex set - valued mapping , then strictly efficient solution set is also connected . as an interesting application of the results in this paper , the connectedness of super efficient solution sets is discussed 本文對集值映射最優化問題引入嚴有效解的概念.證明了當目標函數為錐類凸的集值映射時,其目標空間里的嚴有效點集是連通的;若目標函數為錐凸的集值映射時,其嚴有效解集也是連通的.作為應用,討論了超有效解集的連通性

The algorithm begins horn a conversion of the weight of link cost with an initial solution set in terms of delay - satisfied multicast trees provided for ga , then the expensive tree links are substituted iteratively with the cheaper ones during the crossover operation so as to get the multicast tree satisfying delay constraint with lowest cost 算法從鏈路代價權值轉化開始,以滿意的時延樹為遺傳算法的初始解集,然后在交叉操作過程中不斷地用低鏈路代價的邊代替樹中高鏈路代價的邊,以求得滿足鏈路代價最優的組播樹。

In the case of infinite domains , it is proven that there exists a maximal solution x “ of a @ x = b such that x * x for every solution x of a @ x = b if the solution set of a @ x = b is unempty and b has an irredundant completely meet - irreducible decomposition . it is also identified that there exists a maximal solution x * of a @ x = b such that x * x for every solution x of a @ x = b if the solution set of a @ x = bis unempty and every component of b is dual - compact and has an irredundant finite - decomposition . in the end , a necssary and sufficient condition that there exists a maximal solution x * of a @ x = bsuch that x * x for every solution x of a @ x = b is given when the solution set of a @ x = b is unempty 當論域為無限集時,證明了如果方程a @ x = b有解且b有不可約完全交既分解,則對方程a @ x = b的每一個解至少存在一個大于等于它的極大解;進一步證明了如果方程a @ x = b有解且b的每一個分量為對偶緊元并有不可約有限交分解,則對方程a @ x = b的每一個解存在一個大于等于它的極大解;最后給出了對方程a @ x = b的每一個解存在一個大于等于它的極大解的一個充要條件及[ 0 , 1 ]格上方程a @ x = b的解集中存在極大解的一個充要條件。

For affirmming holding this property , the existing common assumptions are that p is bounded or the leader ' s objective function is bounded from below over p , etc . these assumptions are not the necessary and sufficient conditions for this property to hold , and also p is not the feasible solution set for the leader ' s programming of the problem , so such assumptions are quite strict , for the fractional bilevel programming problem , literatures concerned with the exact penalty function formulation are few 為了保證這一性質,一般就要求假設允許集p有界或者外層目標函數在p上有下界。而允許集p并非是所研究問題的外層規劃的可行集,上述有界性假設也并非是上述性質存在的充要條件,這樣的假設條件是比較嚴格的。對于分式雙層規劃問題的恰當罰函數的研究則少之又少了。
