If you have learned how to obtain a solution with the calculus functions, you are almost done OpenOffice has a new nonlinear solver plugin which uses completely different methods of finding solutions to optimization problems than the steepest-descent methods used in Excel's solver. From your description it sounds like your data has a lot of outliers. For that you need some sort of robust fitting I have an issue with my solver add-in. When trying to solve I get the error 53: Solver32.dll not found. After hours lost on forums, I finally managed to fix the problem by repairing the office suite ( control panel / uninstall / right click on Microsoft office / modify / repair online ) Hello, I have recently had a problem with excel's solver (until last week I never had a porblem). When fitting a data set (trying to minimize my target cell), the solver says that either it has found a solution or that the data doesn't converge. When I run the solver again, my target cell is further reduced or the cells don't converge again According to Frontline Solutions (maker of Solver), it is not compatible yet (as of June 2015). I reinstalled Excel 2013 and was not able to get Solver to work. I reinstalled, repaired, deleted the Solver Files, all to no avail. I gave up and was going back to Excel 2010. 2016 had disabled 2010
Alf, the main problem is that when I run the solver with all the constraints as binary it takes FOREVER to find a solution. But apparently if you convert all the constraints to decimals, the solver works quickly. The problem is though, you can't set a limit to how many screens solver chooses when the constraints are in decimal-form The version of Solver that ships with Excel can generate three reports: an Answer report, a Sensitivity report, and a Limits report. These reports are described in the following discussion. Discussion. Solver's three reports are helpful when interpreting the results obtained by Solver I'm using Excel 2007 on Windows 7. Starting this morning, after I encountered a programming problem, whenever I try to start Excel I get a message that says SOLVER.XLSM is already open. Reopening will cause any changes you made to be discarded. Do you want to reopen SOLVER.XLAM? I have tried answering Yes and No. I've rebooted my computer

What appears to happen is the solver is free to change the free variable, but changing it does not invoke the excel iterative solver to then resolve the entire sheet. The effect of this is that no matter what the solver changes the free variable cell to, it has no affect on the cost function and thus exits early Simply go to Excel Options -> Add-Ins -> Manage Excel Add-Ins -> Select Solver Add-In. Solver then shows up in the Data tab. In order tell Solver what we'll want to solve for, we'll need to set up a network problem for the scenario Solver; advantages of the Excel Solver in linear programming, and three numerical examples outlining the steps involved in ca rrying out adjustment of Solver to solve the linear programming problems This example uses the Solver functions to maximize gross profit in a business problem.
