OpenSolver is released as open source code under the GPL. Development of OpenSolver is made easier by the excellent Excel Name Manager which displays all the hidden worksheet names used to store an optimization model. Current development is lead by Jack Dunn from MIT. Kat Gilbert also made valuable contributions to the code while working as a summer student. OpenSolver is being developed by Andrew Mason in the Department of Engineering Science at the University of Auckland,В and Iain Dunning. However, OpenSolver is still a great tool for simpler models, or spreadsheets that must be compatible with the built-in Solver. SolverStudio is much better and faster for large problems. Check out the screen shots to see how it works. This approach provides a much better modelling solution for complex optimisation problems. The SolverStudio interface is fully Excel-based, with the model being edited and run from Excel and stored inside the Excel file. The latest release allows GAMS and AMPL modesl to be solved in the cloud using the excellent free NEOS servers. Available as a free download, SolverStudio lets you use Excel to edit, save and solve optimisation models built using modelling languages such as the Python-based PuLP, AMPL, GAMS, GMPL, COOPR/Pyomo and GurobiвЂ™s Python interface. SolverStudio is a free alternative to OpenSolver that is better suited to larger problems. Version details (and dates of updates) are shown on the blog page.

You can download OpenSolver.zip (which is hosted on our Open Solver Source Forge site). However, please give it a go and let us know of any problems so we can fix them. This means we cannot guarantee that the latest release will work on old versions. Note that we do not check our code against otherВ versions of Excel or Windows/Mac than these.

We currently test against Excel 2010/2013/2016 on Windows 7 and Windows 10, and Excel 2011/2016 on OS X 10.7 through 10.11.

OpenSolver has been developed for Excel 2007/2010/2013/2016 (including the 64bit versions) running on Windows, and supports Excel for Mac 2011 on Mac OS X, with limited support for Excel for Mac 2016. A modelling tool that we think improves on the built-in Solver window.

An algorithm to build and update the model only using information present on the sheet.

A fast QuickSolve mode that makes it much faster to re-solve your model after making changes.

A built-in model visualizer that highlights your modelвЂ™s decision variables, objective and constraints directly on your spreadsheet.

OpenSolver is free, open source software.ДЄs well as providing replacement optimization engines, OpenSolver offers:.

No artificial limits on the size of problem you can solve вЂ“ have as many variables and constraints as your computer memory allows (but be aware that large problems can be slow to solve).

Compatible with your existing Solver models, so there is no need to change your spreadsheets.

OpenSolver offers a range of solvers for use in Excel, including the excellent, Open Source, COIN-OR CBC optimization engine which can quickly solve large Linear and Integer problems.

OpenSolver provides the following features: Recent developments are courtesy of Jack Dunn at MIT. It is developed and maintained by Andrew Mason and students at the Engineering Science department, University of Auckland, NZ. OpenSolver is an Excel VBA add-in that extends ExcelвЂ™s built-in Solver with more powerful solvers. OpenSolver for Google Sheets see our dedicated OpenSolver for Google Sheets page for more info on the Google Sheets versions of OpenSolver.Д¬OIN-OR Cup Winner: We are pleased to announce that OpenSolverВ is the winner ofВ the 2011 INFORMS COIN-OR Cup sponsored by IBM.

OpenSolver is also available for Google Sheets OpenSolver 2.9.4 Beta Release version is now also available for download. The latest stable version, OpenSolver 2.9.3() is available for download this adds support for using Gurobi 9.0 as a solver. Welcome to OpenSolver, the Open Source linear, integer and non-linear optimizer for Microsoft Excel. OpenSolver uses the COIN-OR CBC optimization engine
