As illustrated in the text, the problem of minimization of the maximum value can be reduced to a standard linear optimization, by adding a new variable and a few modifications to the model. What is a NullReferenceException, and how do I fix it? Abc, Pythoncvxpycvxpy, , 1 x Kevin, @Peter: Thanks! As illustrated in the text, the problem of minimization of the maximum value can be reduced to a standard linear optimization, by adding a new variable and a few modifications to the model. The fact that the dual variable is non-zero also tells us that if we tighten x-y >= 1, (i.e., increase the right-hand side), the optimal value of the problem will increase..
