# Rješavač

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.

To access this command...

#### From the menu bar:

Choose Tools - Solver.

#### From the tabbed interface:

Choose Tools - Solver.

On the Tools menu of the Tools tab, choose Solver.

#### From toolbars:

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

- Maximum: Try to solve the equation for a maximum value of the target cell.

- Minimum: Try to solve the equation for a minimum value of the target cell.

- Value of: Try to solve the equation to approach a given value of the target cell.

  Enter the value or a cell reference in the text field.

### 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.

- Cell reference: Enter a cell reference of the variable.

  Click the Shrink button to shrink or restore the dialog. You can click or select cells in the sheet. You can enter a cell reference manually in the input box.

- Operator: Select an operator from the list. Use Binary operator to restrict your variable to 0 or 1. Use the Integer operator to restrict your variable to take only integer values (no decimal part).

- Value: Enter a value or a cell reference. This field is ignored when the operator is Binary or Integer.

- Remove button: Click to remove the row from the list. Any rows from below this row move up.

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.

### Opcije

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.

### Solve

Click to solve the problem with the current settings. The dialog settings are retained until you close the current document.

## Za rješavanje jednacine sa razrješivacem.

Cilj procesa razrješivanja je pronalazak vrijednosti varijabli jednacine koja rezultira u optimiziranoj vrijednosti u ciljanoj celiji, zvanoj i "objective"=cilj, smjer. Možete odabrati da li ce vrijednost u ciljanoj celiji biti minimalna, maksimalna ili blizu zadane vrijednosti.

Pocetne vrijednosti varijable se unose u pravougaoni skup celija, koju unosite Mijenjajuci celije u kutiju.

Možete definisati seriju uslova koji postavljaju zabrane za neke celije. Na primjer, možete postaviti zabranu da jedna od varijabli ili celija ne smije biti veca od ostalih varijabli, ili ne veca od zadane vrijednosti. Takode možete definisati zabrane da jedna ili više varijabli mora biti cijeli broj (bez decimala), ili binarna vrijednost (gdje su dozvoljene samo 0 i 1).

## 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.

Tu je također lista ograničenja koja možete koristiti da ograničite mogući okvir rješenja ili da kažnjavate određene uslove. Međutim, u slučaju naprednih rješavača DEPS i SCO, ova ograničenja se također mogu koristiti da se specificiraju veze sa varijablama problema. Zbog slučajne prirode algoritma, ovo je visoko preporučeno i daje gornje granice (a u slučaju da je isključena opcija "Pretpostavi ne-negativne varijable" također i donje) za sve varijable. One ne moraju biti blizu trenutnog rješenja (koje je vjerovatno nepoznato) ali trebaju dati grubu indikaciju očekivane veličine (0 ≤ var ≤ 1 ili možda -1000000 ≤ var ≤ 1000000).

Veze su specificirane izborom jedne ili više varijabli (kao razmak) na lijevoj strani i unošenjem numeričke vrijednosti (a ne ćelije ili formule) na desnoj strani. Na taj način možete izabrati jednu ili više varijabli da budu Cijeli broj ili samo Binarni.
