If you add a constraint to an optimization model, and the previously optimal solution satisfies the new constraint, will this solution still be optimal with the new constraint added?

Yes, this solution will still be optimal with the new constraint added.

Step-by-step explanation:

An optimization model is a translation of the key characteristics of the business problem you are trying to solve. The model consists of three elements: the objective function, decision variables and business constraints.

How do I create an optimization problem?

Optimization Problem Setup Choose a Solver. Choose the most appropriate solver and algorithm. Define Objective Function. Define the function to minimize or maximize, representing your problem. Define Constraints. Provide bounds, linear constraints, and nonlinear constraints. Set Options. Set optimization options. Parallel Computing.
