... points A or C, and the values of the distance at the points A, C are greater than the values of the distance at the points E, H, I, we get the desiredstrict inequality and this part of the proof ... ∅.(iv) It is left to the reader, being an immediate consequence of the de nitions and of the hypothesisthat C() = ∅. For the next theorem and throughout the rest of the section, we will assume ... is obtained for the maximum values of |u| or |v|. Henceit is sufficient to analyze the behavior of the distance d(q, t) on the border of the feasibility set.In order to prove the desired inequality,...
