Frontline Systems is pleased to offer the Large-Scale GRG Solver Engine Version 8.0 for Microsoft Excel. The Large-Scale GRG Solver is a new field-installable Solver Engine that "plugs into" the Premium Solver Platform for Excel, and takes advantage of its new Polymorphic Spreadsheet Interpreter.  You can also use it with our Solver Platform SDK to develop applications in a programming language, for one license price!  It extends the power of both Platforms to handle smooth nonlinear optimization problems of up to 4,000 variables and 4,000 constraints in its Standard version, or up to 12,000 variables and 12,000 constraints in its Extended version. It solves global optimization problems using the "multistart" or "clustering" methods available in both Platforms.  And it supports integer variables and "alldifferent" constraints in both Platforms.
 

Fully Compatible

The Premium Solver Platform is 100% upwardly compatible with the standard Excel Solver. It appears when you select the Tools Premium Solver... menu choice; you'll see a familiar Solver Parameters and Solver Options dialog with many new features. Your existing models can be solved with no changes, faster and more easily than before -- with any appropriate Solver engine for the Premium Solver Platform, including the Large-Scale GRG Solver Engine! And your VBA code designed to control the standard Solver will work as-is with the Premium Solver Platform.

Greater Speed and Capacity

You'll be able to solve smooth nonlinear optimization problems twenty to sixty times larger than the standard Excel Solver -- up to 4,000 variables and 4,000 constraints in the Standard version, or up to 12,000 variables and 12,000 constraints in the Extended version of the Large-Scale GRG Solver Engine.  To handle such large problems, the Large-Scale GRG Solver Engine uses sparse matrix storage methods and advanced methods for maintaining numerical stability.

The Large-Scale GRG Solver can use the new Polymorphic Spreadsheet Interpreter in the Premium Solver Platform to obtain partial derivatives of the problem functions (the Jacobian matrix) at each major iteration or Trial Solution.  This yields huge benefits in speed and accuracy -- up to ten times faster or more than without the Polymorphic Spreadsheet Interpreter!

New Options and Tolerances

The Large-Scale GRG Solver offers several new options and tolerances to improve speed and give you better control of the solution process. The Recognize Linear Vars option allows the Large-Scale GRG Solver to take advantage of linearly occurring variables (often found in a large problem that is nonlinear overall), to save time in computing the Jacobian matrix.

If you've ever had problems with trial solutions that included small violations of the bounds you place on variables (sometimes generated by the standard GRG Solver), you'll appreciate the ability to control this behavior with the Relax Bounds on Variables option in the Large-Scale GRG Solver.

The Bypass Solver Reports option allows you to save time on runs when you don't need to produce report information. Other new options and tolerances control the multistart methods for global optimization.

Comprehensive User Guide

In addition to the User Guide that comes with the Premium Solver Platform, you'll receive our Solver Engine User Guide that describes several field-installable Solver engines, including the Large-Scale GRG Solver.  This guide provides complete information on Large-Scale GRG Solver options, the various messages which the Large-Scale GRG Solver can return, how to diagnose problems, and how to control the Large-Scale GRG Solver from VBA in Excel, or from our Solver Platform SDK.

Annual Support Contracts.  An Annual Support Contract for the Large-Scale GRG Solver V8.0 is required for the first year, and at all times in order to obtain software upgrades and technical support beyond basic installation assistance.  An Annual Support Contract includes:

Evaluation Versions.  If you want to "try before you buy," simply register by filling out a simple form, then download and run the V8.0 Engine Setup program.  If you don't already own the Premium Solver Platform V8.0 (which is required in order to run the Large-Scale GRG Solver Engine), you can also download and run the V8.0 PSP Setup program.  You'll receive an evaluation license code which will allow you to use a full featured, full capacity, full speed version of the Premium Solver Platform and the Large-Scale GRG Solver Engine 15 days, free of charge.  You can also download and run the V7.2 SDK Setup program, and use the Solver Platform SDK with the Large-Scale GRG Solver Engine for 15 days.

Product Upgrades.  If you own an older version of the Premium Solver Platform or the Solver Platform SDK and the Large-Scale GRG Solver Engine, you'll receive an automatic upgrade to V8.0 at no extra charge if you have a current Annual Support Contract (if you aren't current, see our instructions for "catching up" on annual support and paying the difference in price).
