Gurobi model object. Commonly used methods include AddVar (adds a new decision variable to the model), AddConstr (adds a new constraint to the model), Optimize (optimizes the current model), and Get (retrieves the value of an attribute).

Objects of this class have unmanaged resources associated with them. The class implements the IDisposable interface.

While the .NET garbage collector will eventually collect an unused GRBModel object, the vast majority of the memory associated with a model is stored outside of the .NET heap. As a result, the garbage collector can't see this memory usage, and thus it can't take this quantity into account when deciding whether collection is necessary. We recommend that you call GRBModel.Dispose when you are done using a model (or use the .NET using statement).
