A.極大化問(wèn)題(原始規(guī)劃)的任意一個(gè)可行解所對(duì)應(yīng)的目標(biāo)函數(shù)值是對(duì)偶問(wèn)題最優(yōu)目標(biāo)函數(shù)值的一個(gè)下界
B.極小化問(wèn)題(對(duì)偶規(guī)劃)的任意一個(gè)可行解所對(duì)應(yīng)的目標(biāo)函數(shù)值是原始問(wèn)題最優(yōu)目標(biāo)函數(shù)值的一個(gè)下界
C.若原始問(wèn)題可行,則其目標(biāo)函數(shù)無(wú)界的充要條件是對(duì)偶問(wèn)題有可行解
D.若對(duì)偶問(wèn)題可行,則其目標(biāo)函數(shù)無(wú)界的充要條件是原始問(wèn)題可行
