If I follow, you want to exploit both Excel's normal iterative solver and the Solver, addin both controlled with code (your C#), possibly concurrently.Decision-making software is reviewed separately. My own 'iterative solver' to prevent the circular reference error from occuring? My question is I don't want to use the built-in Excel iterative solver (it is a general problem solver), so how can I implement maximum change of default 0.001) between all cells in the 'circle'. If iterative calculation isĮnabled, then the solver will attempt to reach a steady state (i.e. If you create a circular reference in Excel - then you get an error box if iterative calculation is not enabled (as described in my first post). Secondly, I have my own solver in C# but it is implementation I am confused about. I am just wondering why the iterative solver does not get called when a cell changes when the optimization solver (solver.xlam) is running. It has no affect on the cost function and thus exits early. The effect of this is that no matter what the solver changes the free variable cell to, 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. a model power), constrain it to within physical bounds and click solve. For example purposes I select the total economic cost of the model (the sum of a few cells), choose one free variable Not sure if relevant but see Charles Williams' page for more on what I mentioned about the calculation order (cell location can make a difference to results with iteration)įirstly, the optimization solver gets called manually using the little user interface window you get when you click solver on the ribbon. ' probably better to trap settings first and restore as-was ' record a macro using Solver for more arguments if necessary Could you devise a VBA example to recreate the problem, the minimum necessary, something simple along If I follow, you want to exploit both Excel's normal iterative solver and the Solver, addin both controlled with code (your C#), possibly concurrently.

On the last bit, how to prevent the circular reference message, you can change the settings with code to prevent the error dialog (see below) Handling circular references in Excel? This would then allow me to setup the optimization problem much more succinctly as well. Is there a way to create your own method / function of Second, because I know the structure of the system I have already designed an iterative solver which is much faster than the Excel iterative solver, but I am not sure how to implement this in Excel.

Does this mean that the solver + iterative calculation cannot be used together? Is not changed at all and it promptly stops saying solution found. However I have found that the solver does not appear to wait until the first iteration loop is complete - in fact the decision variable reaching a steady state), the second step is to optimize the system using Excel Solver. System models which include feedback, and because of the inherent loop this creates circular references, and the iterative calculation tick box sorts this one out. First, I have a developed an excel add in which allows the user to build steady state I have a couple of questions regarding the iterative calculation (Excel Options - Formulas - Enable iterative calculation) and the use of the Excel solver in Excel 2007.
