WebAdd a constraint of the form. t 1 − t 2 = x. where t i ≥ 0. The Simplex Algorithm will set t 1 = x and t 2 = 0 if x ≥ 0; otherwise, t 1 = 0 and t 2 = − x. So t 1 + t 2 = x in either case. On the face of it, this trick shouldn't work, because if we have x = − 3, for example, there are seemingly many possibilities for t 1 and t 2 ... Websolving binary integer LPs and a fast algorithm for solving online LP problems.
