Webb26 apr. 2024 · The first argument in the function represents the name we want to give to our model. The second argument tells our model whether we want to minimize or maximize our objective function. model = LpProblem ("Supply-Demand-Problem", LpMinimize) You can use LpMaximize instead incase you want to maximize your objective function.
