The OptimizationModel class serves as the abstract base class for classes that represent optimization models.

A model has variables and constraints. They are made available through the Variables and Constraints properties. These collections are indexed by name and by position. The types of constraints that are allowed depend on the concrete class.

OptimizationModel instances cannot be created directly. Instead, create an instance of one of the derivived classes:

The Solve method solves the optimization model using a dual Revised Simplex Method. Note that this operation can take a long time for large problems or difficult problems. Most problems up to several hundred variables are solved within a fraction of a second. The Status property returns a OptimizationModelStatus value that indicates the result of the calculation. A value of Optimal indicates an optimal solution was found.

The Solve method returns a Vector containing the optimal values for the variables. The values of the variables are also avaialble through the Value property of the variables. The OptimalValue property returns the optimal value.
