Assume the following linear problem: min c 1 x 1 + c 2 x 2 + x 3 x 3 subject to x 1 + 2 x 3 = 2 x 1 , x 2 0 minc 1 x 1 +c 2 x 2 +x 3 x 3 subject to x 1 +2x 3 =2 x 1 ,x 2 0 for which we assume we know that ( 2 , 0 , 0 ) (2,0,0) is a solution. Mark the condition for the dual variable that follows from complementarity slackness. The following multiple-choice options contain math elements, so you may need to read them in your screen reader's "reading" or "browse" mode instead of "forms" or "focus" mode. Choice 1 of 3: y 1 = c 1 y 1 =c 1 Choice 2 of 3: 2 y 1 = c 3 2y 1 =c 3 Choice 3 of 3: y 1 = c 2 y 1 =c 2
