Frontline Systems is pleased to offer the LGO Global Solver Engine Version 6.5 for Microsoft Excel. The LGO Global Solver is a new field-installable Solver Engine that "plugs into" the Premium Solver Platform. It is designed for global optimization of problems with any continuous (convex or non-convex) functions, with up to 1,000 variables and 1,000 constraints.  It also supports integer variables and "alldifferent" constraints in the Premium Solver Platform V6.5.
 

Fully Compatible

The Premium Solver Platform is 100% upwardly compatible with the standard Excel Solver. It replaces the standard Solver and appears when you select the usual Tools 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 LGO Global Solver Engine! And your VBA code designed to control the standard Solver will work as-is with the Premium Solver Platform.

Solve a Wide Range of Global Optimization Problems

With the LGO Global Solver, you can solve nonlinear problems more general than the Premium Solver Platform's built-in GRG Solver, including problems with functions that are continuous but not necessarily smooth.  And the LGO Global Solver is designed specifically for global optimization of multiextremal models (models with many locally optimal solutions).

Greater Speed and Capacity

You'll be able to solve global optimization problems considerably larger than the problems handled by the Premium Solver Platform itself -- up to 1,000 variables and 1,000 constraints.  (Please note:  The very general class of models handled by LGO includes problems that may be very difficult to solve, even in low dimensions, by any known method.  The LGO Solver Engine Options dialog lets you control heuristic methods that will often greatly speed up process of finding a good solution, but this means giving up a guarantee of finding the true global optimum.)

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 LGO Global Solver.  This guide provides complete information on LGO Global Solver options, the various messages which the LGO Global Solver can return, how to diagnose problems, and how to control the LGO Global Solver from VBA in Excel, or from our Solver Platform SDK.

Annual Support Contracts.  An Annual Support Contract for the LGO Global Solver V6.5 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 V6.5 Engine Setup program.  If you don't already own the Premium Solver Platform V6.5 (which is required in order to run the LGO Global Solver Engine), you can also download and run the V6.5 PSP Setup program.  Follow the installation instructions to obtain 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 LGO Global Solver Engine 15 days, free of charge.

Product Upgrades.  If you own an older version of the Premium Solver Platform and the LGO Global Solver Engine, you'll receive an automatic upgrade to V6.5 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).
