For example, enter the value 0 into cell A2 and repeat steps 5 to 9. Excel finds the other solution if you start with an x-value closer to x = -1. Goal Seek is an inbuilt function in Excel that searches for a solution to a model/formula by iteratively trying source cell values until a solution is found. Click in the 'By changing cell' box and select cell A2. Click in the 'To value' box and type 24.5Ĩ. On the Data tab, in the Forecast group, click What-If Analysis.ħ. You can use Excel's Goal Seek feature to obtain the exact same result. But what if we want to know x for any given y? For example, y = 24.5. Finally, you can choose the reports you want to generate in the Reports box.3.To restore the original data, click Restore Original Values. (This means that the values for your decision variables have been altered, with the corresponding changes to the cells defining the objective function and constraint functions. To keep the solution values on the worksheet, click Keep Solver Solution in the Solver Results dialog box.When you are done specifying the constraints, the solver parameters box should look as follows:.So for our first constraint, we would enter C1 in the Cell Reference box, choose In the Constraint box, enter the right hand side of the constraint.In the cell Reference box, enter the cell reference for the constraint.This will bring up the following dialog box: In the Subject to the Constraints box, enter any constraints you want to apply.

To have Solver automatically propose the adjustable cells based on the target cell, click Guess. Where To Download Mastering Excel Goal Seek Solver Mastering Excel Goal Seek Solver Excel Goal Seek Explained in Simple Steps How to use the Goal Seek function in. (You can drag the 1 in A2 down while holding the Ctrl key). You can specify up to 200 adjustable cells. First you need to enter your required X values in a column. The adjustable cells must be related directly or indirectly to the target cell.

In the By Changing Cells box, enter the cell references for each of the decision variables, separating nonadjacent references with commas.

To have the target cell be a certain value, click Value of, and then type the value in the box. To have the value of the target cell be as small as possible, click Min.

To have the value of the target cell be as large as possible, click Max.

(Shortcut: Click on the Set Target Cell box, then click on cell B1 in the spreadsheet).

In the Set Target Cell box, enter the cell reference for the objective function.

If the Solver command is not on the Tools menu, you need to install the Solver add-in. In Excel, you can use Solver to find an optimal value (maximum or minimum, or a certain value) for a formula in one cell called the objective cell.

Having defined all of the functions, we now need to tell the solver how to use these functions.

For example, define C1 by the expression =A1+2*A2, and define C2 by =2*A1-A2.

Next define each of the explicit constraint functions.

For example, we can define cell B1 by click on cell B1 and then typing =2*A1+3*A2 in the formula bar.

Next define the objective function in another cell.

In these example, we shall use cell A1 to represent x_1 and A2 to represent x_2.

First choose cells to represent your decision variables.
