WebNov 12, 2024 · We want a constraint x1 <= 0 to exist when x2 > 2. When x2 <= 2 no such constraint exists (x1 can be either positive or negative). First we create a binary variable: b1 = LpVariable("b1", cat='Binary') Choose this to represent the condition x2 > 2. The easiest way to achieve this adding a constraint: M1 = 1e6 prob += b1 >= (x2 - 2)/M1 WebYou need to model disjunctive constraints. I will assume that variable x is constrained to lie in L 1 ≤ x ≤ U 1 or L 2 ≤ x ≤ U 2. For instance, if you have the constraint 2 ≤ x ≤ 5, …
