Deletes an existing constraint. Equivalent to clicking Solver in the Data | Analysis group and then clicking Delete in the Solver Parameters dialog box.

Before you use this function, you must establish a reference to the Solver add-in. In the Visual Basic Editor, with a module active, click References on the Tools menu, and then select the Solver.xlam check box under Available References. If Solver.xlam does not appear under Available References, click Browse and open Solver.xlam in the \office14\library\Solver subfolder.


SolverDelete(CellRef, Relation, FormulaText)

CellRef   Required Variant. A reference to a cell or a range of cells that forms the left side of a constraint.
Relation   Required Integer. The arithmetic relationship between the left and right sides of the constraint. If you choose 4, 5 or 6, CellRef must refer to decision variable cells, and FormulaText should not be specified.


Arithmetic relationship








Cells referenced by CellRef must have final values that are integers.


Cells referenced by CellRef must have final values of either 0 (zero) or 1.


Cells referenced by CellRef must have final values that are all different and integers.

FormulaText   Optional Variant. The right side of the constraint.


This example loads the previously created Solver model stored on Sheet1, deletes one of the constraints, and then solves the model again.

Worksheets("Sheet1"). Activate
