(Click on the code excerpt for a full-size image.) In the VB.NET code excerpt below, we define a function NLPEvaluator_OnEvaluate() that accesses elements of the model through Solver SDK objects.

Call the Optimize() method in your program to find the optimal solution.Īssuming that you have Visual Studio and Solver Platform SDK installed, and you've opened a new or existing project, the next step is to define a VB.NET function where the formulas for the objective function and the constraints are calculated.

Use SDK objects in your program to tell the Solver about your decision variables, objective and constraint calculations, and desired bounds on constraints and variables.

Similarly, create assignment statements in your program to calculate the left hand sides of your constraints.

Create an assignment statement in your program, that calculates the objective function in your model.

Create a variable in your program to hold the value of each decision variable in your model.

NET program (the steps in another Windows programming language would be very similar): Follow these steps to define and solve the Product Mix problem in a Visual Basic.
