ILOG, Brown University and MIT Press announce new global optimization

Book Numerica describes mathematical breakthrough; ILOG Numerica software
tool available now

SAN DIEGO--(BUSINESS WIRE)--May 5, 1997--At the INFORMS conference held
here today, ILOG, Brown University and MIT Press jointly announced a new
global optimization technique called Numerica.

Developed at Brown by Dr. Pascal Van Hentenryck and described in the book
Numerica by Van Hentenryck, Laurent Michel and Yves Deville, the new
technique is also implemented in a new software tool called ILOG Numerica
and now available in early release form, online from ILOG.

"Ilog Numerica is a unique and powerful tool for global optimization in
business and academia," said Jacob Feldman, director of IntelEngine, a New
Jersey-based optimization software consulting firm. "Its modeling language
allows you to naturally express complex business problems in terms of
nonlinear constraints. Its powerful combination of numerical methods with
constraint satisfaction techniques provides very efficient search
algorithms. And you can get and customize solutions via its simple
graphical user interface without being a programming or math guru."

"Numerica incorporates recent advances in the fields of constraint-based
programming and numerical analysis into a powerful and relatively simple
desktop software tool," explained David Taber, vice president of marketing
at ILOG. "Highly nonlinear problems, which were previously beyond the
scope of all but the most powerful computer systems, can now be solved
quickly and easily on a standard PC.

"For example, the fields of chemical and electrical engineering frequently
present nonlinear problems which may by nature have many possible
solutions or no possible solution, and thus frustrate traditional
mathematical models. These can now be modeled and solved easily with
Numerica. The beta release of ILOG Numerica is available now, free of
charge through September 1997, for the major Unix and Windows platforms,
to the first 500 downloads from"

"MIT Press is pleased to see commercial implementation of advanced
technology from research," said Bob Prior of MIT Press. "We believe ILOG
Numerica and our new book on Numerical Optimization will be perfect
complements to each other."

"Numerica is a very impressive system, incorporating the latest technology
for smooth constraint and optimization problems, and a significant
milestone in computer science and applied math," said William J. Older of
the Computing Technology Lab, Northern Telecom, in Ottawa. "The authors
provide a manual for users of the Numerica system (solution of
semi-algebraic and some semi-analytic variety problems over the reals
using interval arithmetic). It is a substantial and useful addition in an
important market."


ILOG is a leading provider of advanced software components for graphics
and resource optimization. ILOG's products enable: high-performance
data-visualization for 2D and 3D user interfaces; constraint-based
reasoning systems for resource optimization, scheduling, logistics and
planning applications; dynamic rule systems for intelligent agents and
real-time data flow control; and component services for integrating C++
modules with real-time and relational data sources. ILOG S.A. was founded
in 1987, now employs approximately 260 people worldwide, and is traded on
NASDAQ NMS under the symbol ILOGY. ILOG is a registered trademark of ILOG
