The Solution Object

The Solution object is a property of the parent Model object and contains all the information stored about the solution for the model. The Solution object properties are only available after the model has been solved.

Collections contained by the Solution Object

Constraints

Returns the Constraints collection for the solution.

Variables

Returns the Variables collection for the solution.

Properties for the Solution Object

IsAvailable

Specifies if the solution values are available for retrieval. (Boolean Property - Read/Write)

IsRangesAvailable

Specifies if the solution ranges are available for retrieval. (Boolean Property - Read/Write)

CSharp Example:


     OptiMax MPL;
     Solver cpxSolver;
     Model planModel;
     Solution planSol;
     ResultType result;

     MPL = new OptiMax();

     cpxSolver = MPL.Solvers.Add("CPLEX");
     planModel = MPL.Models.Add("Planning");

     string WorkingDirectory = "c:\\mplwin4";
     string modFilePath = WorkingDirectory + "\\" + "Planning.mpl";
     planSol = planModel.Solution;

     result = planModel.ReadModel(modFilePath);
     result = planModel.Solve(cpxSolver);
     Console.WriteLine("ResultString     = " + planSol.ResultString);
