How to Undo Solver in Excel

Resetting Solver to Default Settings

To revert changes made by Solver in Excel, use the SolverReset function. This function clears all cell selections, constraints in the Solver Parameters dialog box, and restores all settings in the Solver Options dialog box to their default values. Ensure the Solver add-in is installed and enabled, with a reference established, before using SolverReset.

Effects of Solver Options on Reverting Changes

Adjusting Solver options influences the solution's nature and accuracy as well as the computation time. To undo changes effectively, understanding these options is crucial. Changes to the options can be undone by resetting them to defaults using the SolverReset function.

Undo Steps in Solver

Solver, an add-in for Excel, is used for what-if analysis by optimizing the value of an objective cell while adhering to constraints on other cells. To undo the adjustments made by Solver to the decision variable cells, which are used in computing formulas in the objective and constraint cells, you can reset Solver settings before defining a new problem.

Use Cases for Excel Solver Undo Feature

Restoring Original Data After Unsatisfactory Optimization

When Solver's optimization results don't meet your needs, you can quickly revert to your starting values. This allows you to preserve your initial dataset and try different optimization approaches without creating backup copies.

Quick Recovery from Input Errors

If you discover you've entered incorrect constraints or selected wrong variables in your Solver model, you can undo the solution and make corrections. This saves time by eliminating the need to rebuild your entire model from scratch.

Solution Comparison Through Easy Reversions

Compare multiple Solver solutions by running an optimization, documenting results, and reverting to original values for the next attempt. This systematic approach helps identify the most effective solution for your optimization problem.

Iterative Model Refinement

Fine-tune your optimization model by running Solver, analyzing results, and undoing changes as needed. This iterative process helps you understand how different parameters affect your solution and achieve better outcomes.

Workbook Data Protection

Before saving your workbook, you can undo Solver changes to maintain the original data integrity. This ensures your base dataset remains unaltered while still allowing for temporary optimization experiments.
