Opens the Solver dialog. A solver allows you to solve mathematical problems with multiple unknown variables and a set of constraints on the variables by goal-seeking methods.

Choose Tools - Solver.

Solver settings

Target Cell

Enter or click the cell reference of the target cell. This field takes the address of the cell whose value is to be optimized.

Optimize results to

By Changing Cells

Enter the cell range that can be changed. These are the variables of the equations.

Limiting Conditions

Add the set of constraints for the mathematical problem. Each constraint is represented by a cell reference (a variable), an operator, and a value.


You can set multiple conditions for a variable. For example, a variable in cell A1 that must be an integer less than 10. In that case, set two limiting conditions for A1.


Opens the Solver Options dialog.

The Solver Options dialog let you select the different solver algorithms for either linear and non-linear problems and set their solving parameters.

Pa resolver ecuaciones con solver

L'oxetivu del procesu solucionador ye atopar estos valores variables d'una ecuación que la resultancia nun valor optimizáu na caxella oxetivu. Usté pue escoyer si'l valor na caxella oxetivu ten de ser el máximu, mínimu, o averase a un determináu valor.

Los valores iniciales de la variable son inxertaos nun rangu de la caxella rectangular que la to tecleas (amiestes) en pa camudar caxelles caxa.

Pue definir una serie de condiciones limitantes pa definir llindar de delles caxelles. Por exemplu, pues definir les limitantes d'una variable o caxella que nun tenga de ser mas qu'otra variable, o nun seya mas qu'un valor dáu. Pues tambien definir les limitantes qu'una o mas variables tien de ser enteros (valores ensin decimales), o valores binarios (onde solo 0 y 1 son dexaos).

Using Non-Linear solvers

Regardless whether you use DEPS or SCO, you start by going to Tools - Solver and set the Cell to be optimized, the direction to go (minimization, maximization) and the cells to be modified to reach the goal. Then you go to the Options and specify the solver to be used and if necessary adjust the according parameters.

There is also a list of constraints you can use to restrict the possible range of solutions or to penalize certain conditions. However, in case of the evolutionary solvers DEPS and SCO, these constraints are also used to specify bounds on the variables of the problem. Due to the random nature of the algorithms, it is highly recommended to do so and give upper (and in case "Assume Non-Negative Variables" is turned off also lower) bounds for all variables. They don't have to be near the actual solution (which is probably unknown) but should give a rough indication of the expected size (0 ≤ var ≤ 1 or maybe -1000000 ≤ var ≤ 1000000).

Bounds are specified by selecting one or more variables (as range) on the left side and entering a numerical value (not a cell or a formula) on the right side. That way you can also choose one or more variables to be Integer or Binary only.
