Overview
The OpenSolver Add-on for Google Sheets lets you solve complex optimization problems from within your Google Sheet. Made by the developers of the popular OpenSolver addin for Microsoft Excel, this add-on brings the same Open Source optimization engine to the cloud!

OpenSolver for Google Sheets uses the excellent, Open Source, SCIP and Glop optimization engines to quickly solve large Linear and Integer problems.  SCIP is one of the fastest non-commercial solvers for mixed integer programs, and Glop is an Open Source Linear Programming solver by the Operations Research team at Google.  We also support using the Open Source COIN-OR Cbc solver via the NEOS optimization cloud, and the Open Source GLPK solver running locally in your browser via GLPK.js.

There are no artificial limits on the size of problem you can solve with OpenSolver.

OpenSolver is free, Open Source software developed and maintained by Andrew Mason and students at the Engineering Science department, University of Auckland, New Zealand.

Detects a linear model as a nonlinear model. What. Should also be able to set the step size/relaxation factor.

this gives completely incorrect answers. I tried to use it for forecasting and it just puts variables at 0 even when i put they must be greater than 0. Useless, don't waste your time.

Can't even solve a linear model reliably. Whoever wrote this doesn't know anything about numerical methods.

Nothing like a solver that sets all variables to zero to minimize the objective without even trying negative variables out lol. Trash. Uninstalling immediately

Yeah. Straight up doesn't work. Using for a rental property model and wanted the monthly payment to be equal to $400 by changing the cell that contained the mortgage rate. Not even close to right answer Uninstalling

This thing is terrible. I gave it the constraints to be greater than 0 and it still tried to divide by 0.

buggy and sometimes doesn't work even with equal number of constraints. I recommend using it with guidance of a professional.

Does not work. Erases previously setup data as you set up your next parameter. Set objective, move to variables, it will erase objective. basically it refereshes with only most recent value set EVERY TIME. what a waste of time!

Needed a basic solver for a class I'm taking, and this did the trick.
