KNITRO Solver Engine - Risk Solver Platform and Solver Platform SDKKNITRO: An Interior Point Nonlinear Solver, Now Including Active Set MethodsSolves very large scale smooth nonlinear problems.Frontline Systems is pleased to offer the KNITRO Solver Engine Version 9.0 for Microsoft Excel. The KNITRO Solver is a new field-installable Solver Engine that "plugs into" Risk Solver Platform and 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 our Solver Platform products to handle smooth nonlinear optimization problems with no fixed limits on the number of variables and constraints. It solves global optimization problems using the "multistart" or "clustering" methods available in the Solver Platform products. And it offers greatly improved performance, especially on problems with integer variables and "alldifferent" constraints, in Version 9.0.
Fully CompatibleRisk Solver Platform and Premium Solver Platform are 100% upwardly compatible from the standard Excel Solver. Your existing models can be solved with no changes, faster and more easily than before. And your VBA code designed to control the standard Solver will work as-is with Risk Solver Platform or Premium Solver Platform and the KNITRO Solver Engine -- just select the KNITRO Solver interactively or in your VBA code. Greater Speed and CapacityYou'll be able to solve smooth nonlinear optimization problems far larger than the standard Excel Solver -- with an unlimited number of variables and constraints -- with the KNITRO Solver Engine. And you'll be amazed at the fast solution times you can obtain: Some nonlinear problems with many hundreds of variables and constraints will solve in just seconds! To handle such large problems, the KNITRO Solver Engine uses sparse matrix storage methods and advanced methods for maintaining numerical stability. The KNITRO Solver takes maximum advantage of the new Polymorphic Spreadsheet Interpreter in Risk Solver Platform and Premium Solver Platform to obtain either first or second partial derivatives of the problem functions (the Jacobian or Hessian matrix) at each major iteration or Trial Solution. New Options and TolerancesThe KNITRO Solver offers several new options and tolerances to improve speed and give you better control of the solution process. The Treat Constraints as Linear and Treat Objective as Linear options allow you to speed up evaluation of the Jacobian or Hessian matrix at each major iteration on NLP problems with all-linear constraints. 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 KNITRO Solver. In Version 9.0, this option setting is adjusted dynamically during the solution process, depending on problem characteristics. 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 GuideIn addition to the User Guide that comes with Risk Solver Platform, you'll receive our Solver Engine User Guide that describes several field-installable Solver engines, including the KNITRO Solver. This guide provides complete information on KNITRO Solver options, the various messages which the KNITRO Solver can return, how to diagnose problems, and how to control the KNITRO Solver from VBA in Excel, or from our Solver Platform SDK.

Annual Support Contracts. An Annual Support Contract for the KNITRO Solver V9.0 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 V9.0 EngineSetup program. If you don't already own Risk Solver Platform or Premium Solver Platform (which is required in order to run the KNITRO Solver Engine), you can also download and run the V9.6 RSPSetup program. You'll receive an evaluation license code which will allow you to use a full featured, full capacity, full speed version of Risk Solver Platform and the KNITRO Solver Engine 15 days, free of charge. You can also download and run the V9.0 SDK Setup program, and use the Solver Platform SDK with the KNITRO Solver Engine for 15 days. Product Upgrades. If you have an older version of Risk Solver Platform, Premium Solver Platform or Solver Platform SDK and the KNITRO Solver Engine, you'll receive an automatic upgrade to V9.0 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).
