Creates, returns, and adds to the invoking model an empty objective function with the sense specified by sense.

This method creates and returns an IObjective object with a zero expression and the specified optimization sense. The new IObjective object is added to the invoking IModel. This method is typically used in an application that applies column-wise modeling to fill in the objective function while creating the variables.

Creates and returns an instance of IObjective representing an objective to optimize the expression expr with respect to the optimization sense indicated by sense and added to the invoking model.

Creates, returns, and adds to the invoking model an empty objective function with the name specified by name and with the sense specified by sense.

Creates and returns an instance of IObjective representing an objective to optimize the expression expr with respect to the optimization sense indicated by sense, assigned the name name, and added to the invoking model.
