Interactive Optimization enables the Solver to re-optimize the model each time the user changes a number on the spreadsheet. Users can move easily between the traditional interactive modeling style and the new functions such as PsiVar(), PsiObj() and PsiCon(), or between the new V7.0 functions for optimization and Risk Solver Engine's functions for simulation. New Function-Based Models and Interactive OptimizationĪlso new in the Premium Solver Platform V7.0 are optimization models defined via functions on the worksheet, and Interactive Optimization. The best integer solutions ('incumbents') for MIP problems, locally optimal solutions for global optimization problems, or best 'final population' members for non-smooth problems solved with the Evolutionary and OptQuest Solvers can be viewed in a worksheet report, or easily accessed in user VBA programs via the Platform's new object-oriented API. The Premium Solver Platform V7.0 and Solver Engines V7.0 can now deliver multiple solutions, not just a single best solution, for integer programming and global optimization problems. Multiple Solutions for Integer Programming and Global Optimization Problems

This means that users can find solutions for much larger, more challenging simulation optimization models in Excel than has been possible with any software before the Premium Solver Platform V7.0. The potent combination of the Premium Solver Platform V7.0 and its multiple Solver Engines with Risk Solver Engine V7.0 for simulation optimization is frequently ten to a hundred times faster than competitive products for Excel. Statistics for any uncertain formula, such as its mean and variance, Value at Risk, and percentiles, are available on the spreadsheet and can be used in the objective and constraints of a V7.0 optimization model. Risk Solver Engine performs Monte Carlo simulation, with thousands of trials, on each change to the spreadsheet.

Models can include random variables, defined by probability distributions, and formulas that depend on these random variables. This is Frontline's first step in a long-term effort to support optimal decision-making under uncertainty, using quantitative models in Excel. When used with Frontline Systems' new Risk Solver Engine V7.0, the Premium Solver Platform V7.0 can solve simulation optimization problems with unprecedented speed. The Polymorphic Spreadsheet Interpreter (PSI Technology) in the Premium Solver Platform V7.0 is faster than ever in model analysis, especially for multi-worksheet models, and supports more Excel features than ever, such as the new built-in functions in Excel 2007. Report generation is typically 5-7 times faster for models of a few thousand variables, and many times faster for larger models. Solution reports, previously limited to 65,536 rows, are now automatically 'wrapped' and may be of virtually unlimited size, even in Excel 2000-2003. In Excel 2007, the Platform V7.0 supports Solver models with 16,384 columns and 1,048,576 rows - far beyond the 256 column and 65,536 row limits in previous Excel releases. Different models may be defined on each worksheet, and each model can include variables and constraints on any sheet in a workbook. The Premium Solver Platform V7.0 supports Solver models spread across multiple worksheets in a workbook, with decision variables and constraints on any worksheet. "I will continue to push the bounds to see if it can solve even larger problems." New Support for Large, Multi-Worksheet Models

The largest contained 2.4 million variables," said Christian Peters from Cornell University. "Using Frontline Systems' Premium Solver Platform and their Extended Large-Scale LP Solver Engine V6.5, I was able to solve several very large linear optimization problems. "But it also delivers new capacity, speed, ease of use, and multiple solutions for users of Excel 2003, XP and 2000."

Trial versions are available for download from "Premium Solver Platform V7.0 is the first optimization software with full support for the new features of Excel 2007, including worksheets of 16 thousand columns and 1 million rows,' said Daniel Fylstra, President of Frontline Systems. Frontline's products are upward compatible with the Solver in Excel and offer a comprehensive solution for businesses seeking to better allocate scarce resources using optimization technology. INCLINE VILLAGE, NV - Aug- Frontline Systems is shipping Version 7.0 of its Premium Solver Platform for Excel, the market leader for spreadsheet optimization, and seven large-scale Solver Engines V7.0 that 'plug into' both the Premium Solver Platform and the Solver Platform SDK V7.0.
