Frontline Systems, Inc

The Solver code is not written by Microsoft, but instead is a product of Frontline Systems Inc. (P.O. Box 4288, Incline Village, NV 89450, www.frontsys.com). Essentially the same code is used in Microsoft Excel Solver, in the Lotus 1-2-3 Solver, and in the Quattro Pro Solver. 

Allan D. Waren, Cleveland State University, for discussion about the Solver algorithms, and Edwin Straver, Frontline Systems Inc., for information about the inner workings of the Solver.
