例句與造句

1. 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(shù)在p上有下界。而允許集p并非是所研究問題的外層規(guī)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(guī)劃問題的恰當罰函數(shù)的研究則少之又少了。
2. It's difficult to find bounded from below in a sentence. 用bounded from below造句挺難的
