WebbThe 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 … Webb25 aug. 2024 · Their signs should be inverted to switch from your form of constraint f (x) >= const to the desired form for the linprog method, which is a less-than-or-equal, i.e. -f (x) <= - const. You are missing the final two constraints. Your proposed minimum is < 0, which is obviously impossible as w = 10*x1 + 15*x2 + 25*x3 is always positive with your ...
