SUMMARY

The maximum number of adjustable cells and constraints that a Solver model can use are listed in the following table.

   Microsoft Excel   Adjustable cells   Constraints
   version
   ---------------------------------------------------

   3.x               200                299
   4.x               200                500
   5.0               200                500
   7.0               200                500
   97                200                unlimited/500*
   98                200                unlimited/500*
   2000              200                unlimited.500*

* If you are working with a linear problem, the maximum number of constraints you can use is unlimited. If you are working with a nonlinear problem, the maximum number of constraints you can use is 500.

MORE INFORMATION

To determine whether a solver problem is linear or nonlinear, click Options in the Solver dialog box. If the Assume Linear Model check box is selected, the problem is linear.
