Versions of OpenSolver released from 2015 also include a new experimental parser that directly translates the formulae in your spreadsheet into a form the solver understands. To create this copy for linear models, OpenSolver uses an iterative process that requires one spreadsheet re-calculation for each decision cell. Most of the solvers need to be given a copy of your model in a form they understand.

This page gives information about the solvers, including its uses and limitations, to help you find the right solver for your problem. We may be able to help steer you in the right direction so you get the results you need to support continuing with the project.OpenSolver supports a wide variety of solvers for use inside Excel, and several different ways in which the solver integrates with the Excel model. If you find yourself in this situation, please do contact us. This is unfortunate, since with the right tools and support the project might have been a great success. The team then ends the project and moves on. Alternatively, they found it was just too hard to use, given the solver didn’t support the programming language they preferred, they couldn’t get support, etc. As a result, they assumed their problem was just too complex to use optimization techniques.

#Linear programming solver for excel free

We have seen cases where someone selected a free solver, tried building a model, and the solver just couldn’t handle the problem. One of the most important questions people tend to ask when they are first exploring solvers is if optimization is a fit for their business. We have a very large library of models and may be able to do a specific comparison. Before you make the choice to use a free solver, we suggest that you look at relative performance on models of similar size and complexity to those that you are likely to want to eventually solve.We’ve seen many situations where free solvers worked well on a small prototype but were unable to handle the production model. This can cause a lot of rework that you may be able to avoid. We want to stress that you should consider future growth in the model.Free solvers tend to struggle with larger and more difficult models, but if a free solver is able to solve your problem now, and you are confident that your problem won’t become more difficult in the future, then a free solve could be a reasonable choice.The model(s) being solved are both small and relatively easy to solve

Gurobi offers both C and C++ APIs, as well as a full range of other APIs, including Python, for you to choose from.

Most free solvers are written in C or C++ and don’t offer other APIs.

While the free trial version of Gurobi (limited to 2000 decision variables and 2000 constraints) or an unlimited temporary evaluation license of Gurobi may suit your needs, if your problem is larger than a trial version allows and/or your time horizon is longer than appropriate for an evaluation version, a free solver can be a good way to get started.

Management may still be trying to determine the role optimization can play in planning and decision making, and the team doing the work is still “getting their feet wet.”

Often times, when a company is first looking at using an optimization solver in their business, there may not be an approved budget.

Below are a few scenarios where you may want to consider a free solver.

However, we don’t mean to give you the impression that free solvers are never the right choice.

When a free solver may be the best choiceĪs you can see from the data above, free solvers tend to struggle with practical models, either failing to solve them at all or solving them relatively slowly. If you are an academic user (student, faculty, or staff) at a degree-granting institution, or if you are currently taking an online course in optimization, please take a look at our Academic page. If you are, we offer several license types of Gurobi completely free to academic users who meet certain criteria. Note, since you are exploring free solvers, our assumption is you are not an academic. when a free solver may be the best choice.relative solver performance comparisons.a list of some of the leading free linear and mixed-integer programming solvers.Specifically, on this page we will cover the following topics: This page is designed to help you better understand your choices among free solvers, their relative performance, and some questions to ask yourself in deciding what type of solver is right for you. We also know that for some situations a free solver might be all that you need. We know there are a range of solvers, free and paid, to choose from. Exploring options among open source solvers
