How do I make Excel Solver more accurate?

Select the Use Automatic Scaling check box to specify that Solver should internally rescale the values of variables, constraints and the objective to similar magnitudes, to reduce the impact of extremely large or small values on the accuracy of the solution process.

In the Cell Reference box, enter the cell reference or name of the cell range whose value(s) you want to constrain.If you click int, integer appears in the Constraint box. If you click bin, binary appears in the Constraint box. If you click dif, alldifferent appears in the Constraint box.

Why is Solver ignoring my constraints?

Open up your Solver menu and click on the Options button. Make sure that the box next to the words “Ignore Integer Constraints” is not checked.If you see this message and your results are non-integer values, it means that one or more of your constraints are either conflicting with other constraints or not possible.

Is Excel Solver accurate?

The default precision is 0.000001. A smaller number of decimal places (for example, 0.0001) indicates a lower degree of precision. In general, the higher the degree of precision you specify (the smaller the number), the more time Solver will take to reach solutions.

What is GRG algorithm?

GRG stands for “Generalized Reduced Gradient”. In its most basic form, this solver method looks at the gradient or slope of the objective function as the input values (or decision variables) change and determines that it has reached an optimum solution when the partial derivatives equal zero.

Does Solver work with if statements?

You can use discontinuous functions such as IF and CHOOSE in calculations on the worksheet which are not dependent on the decision variables, and are therefore constant in the optimization problem. But any discontinuous functions that do depend on the variables will likely cause problems for the Solver.
