Nettet22. aug. 2024 · The reason is that in linear programming your constraints must be linear, and your solution space must be convex. The constraint of either 1 or 0 is not linear. The solution space {0, 1} in the real numbers is not convex (proof: the average of 0 and 1 is .5 and is not in the solution space). The solver you're using in your code runs the Simplex ...

It is clear that the feasible region of your linear program is not convex, since x=0 and x=1 are both feasible, but no proper convex combination is feasible. As a result, it is provably impossible to model this with a linear program. That being said, it is easy to model this if you ... how to use snap on computerNettet22. jul. 2024 · The resulting infeasibilities are taken on by the artificial variables and they are basic at the beginning of Phase I.
