This add-in is extremely useful for finding the roots of equations. You only need to add constraints to cells which are going to be changed. () and you can obtain more information about this add-in from their web site. This add-in is licensed to Microsoft by Frontline Systems Inc. This can also be used to find combinations of variables that may provide a maximum or minimum result. If you want to limits the changes that Excel can make to a cell value or a target value you can add a constraint. Total expenditure must be less that the budget available (F8 <= G13) The number of ads in each publication (E3: E8)Ĥ) Constraints - Solver adjusts the values according to these conditions. Set target cell (F9) mimising the total expenditureģ) Variables / Adjustable Cells - Solver changes these cells to new values. Reset All - Clears the current problem settings, and resets all settings to their original values.Ģ) Target Cell - Solver adjusts the values based on this formula. Options - Displays the Solver Options dialog box, where you can load and save problem models and control advanced features of the solution process. Retains any changes you made by using the Options, Add, Change, or Delete buttons. Solve - Starts the solution process for the defined problem.Ĭlose - Closes the dialog box without solving the problem. Subject to the Constraints - Lists the current restrictions on the problem.Īdd - Displays the Add Constraint dialog box.Ĭhange - Displays the Change Constraint dialog box.ĭelete - Removes the selected constraint. Guess - Guesses all nonformula cells referred to by the formula in the Set Target Cell box, and places their references in the By Changing Cells box. The adjustable cells must be related directly or indirectly to the target cell. If you want a specific value, type it in the box.īy Changing Cells - Specifies the cells that can be adjusted until the constraints in the problem are satisfied and the cell in the Set Target Cell box reaches its target. This cell must contain a formula.Įqual To - Specifies whether you want the target cell to be maximized, minimized, or set to a specific value. Set Target as - Specifies the target cell that you want to set to a certain value or that you want to maximize or minimize.

This add-in has several uses, one of which is to solve both linear equations. conditions) that must be met for the solution to be valid. This add-in also allows you to provide one or more constraints (*i.e. The Goal Seek command can be used for finding simple target values but this add-in can be used for more complex problems This add-in can be used to solve formulas that contain several variables and is an extension to the built-in Goal Seek (one variable) functionality. The Solver add-in allows you to perform "what if" calculations based on several variables. This is an additional add-in that can be loaded when necessary.
