What’s new in Xpress Optimization Suite 7.1
3 November, 2010

The Xpress
Optimization Suite
helps organizations
solve bigger problems,
design applications
faster, and make evenbetter decisions in
virtually any businessscenario.

New in Xpress 7.1 is the unique ability to support ultra-large-scale
optimization by adding distributed modeling capabilities and true 64bit
support to solve problems where the huge number of coefficients exceed thelimits of most products, Xpress 7.1 also significantly improves performance on
both academic benchmarks and real world client problems; keeping it wellplaced among the fastest solver offerings.
FICOTM Xpress Optimization Suite is the premier mathematical modeling andoptimization software suite in the world, with the best tools available to aid
the development and deployment of optimization applications that solve
complex, real-world challenges. The improvements in Xpress 7.1 in detail:

Unique features for solving ultra-large scale optimization problems
Solving large, complex optimization problems can be a daunting task. Conquering themeffectively, however, can be the difference between success and failure in today’s highly
competitive marketplace. FICO Xpress Optimizer 7.1 has introduced new features that make large
scale optimization problems more management and help turn the unsolvable into solvable.
MIP performance across releases• Solve much bigger problems with true 64bit
support
The possibilities are limitless with the enhanced
optimization and modeling support for solving
ultra-large-scale models where the number ofcoefficients can exceed 2 billion.
• Solve large problems faster with distributedmodeling and solving
Cut solution times dramatically by leveraging
distributed execution of Mosel models that can
now be controlled from a master model acrossa heterogeneous set of machines.
For more information, please read our whitepapers on large scale optimization and parallel anddistributed modeling available for download at http://optimization.fico.com.
Additional improvement to the optimization engines:– Dramatically enhanced parallel, mixed integer and mixed integer quadratic solvers– More stable and robust nonlinear algorithms including SLP– Improved branching strategies– New cuts like Clique Implied Bound Cuts and Conflict Cuts
– Support for finding Mixed Integer Irreducible Subsets (MIIS)– A Matlab interface is available

What’s new in Xpress Optimization Suite 7.1

Design fasterXpress 7.1 enables organizations to build applications faster than before and design them tomatch the way the business works. IVE visual development environment for Mosel has been
improved so it’s easier for developers to get new optimization initiatives to market in less time.
IVE project explorer

The newest release of Xpress features:• Improved modeling language and development environment that simplifies
the design of complex optimization models.
• Improved drag-and-drop editor that increases productivity through rapid
prototyping and faster deployment.
• Project functionality has been added to IVE. A project is a collection ofrelated files (Mosel, XAD resources, data,...) together with IVE configuration.

Make better decisions
Xpress 7.1 includes a new version of Xpress-Mosel software, a robust modeling and programming
language that lets users model and examine multiple solutions to find the ideal choice for any
given business scenario. As a result, it’s easier to choose the solution that best aligns to businessgoals.

The newest release of Xpress features:• Added functionality for distributed modeling andsolving. It is now possible to start other Mosel
instances (either on the same machine in a
separate process or on a remote host) and executecommands remotely on them (e.g. compile, load,and execute models).
• Simplified and more robust data exchange
capabilities between Mosel and applications.
• XML interface.
