Nettet22. jun. 2024 · So let's assume you want the constraint: x == 0 OR 1 <= x <= 2. It is clear that the feasible region of your linear program is not convex, since x=0 and x=1 are … Nettet24. jul. 2015 · 3 Answers. All constraints in a linear program are convex (if x, y satisfy the constraints, then t x + ( 1 − t) y also does for all 0 ≤ t ≤ 1 ). The constraint a + b > 3 is not convex, since ( 4, 0) and ( − 4, 0) are both solutions while ( 0, 0) is not. It is also not closed, which is another reason why you cannot use it in a linear ...

NettetIn operations research, the Big M method is a method of solving linear programming problems using the simplex algorithm.The Big M method extends the simplex algorithm to problems that contain "greater-than" constraints. It does so by associating the constraints with large negative constants which would not be part of any optimal solution, if it exists. NettetHere is the trick. Add 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 ...
