COLLEGE STATION, Texas, April 12, 2011 - Carl Laird,
assistant professor in the Artie McFerrin Department of Chemical
Engineering at Texas A&M University, has been named recipient
of the prestigious Wilkinson Prize for Numerical Software.
Laird will receive the international award along with colleague
Andreas Waechter of the IBM Thomas J. Watson Research Center for
their development of IPOPT, a software library for solving
nonlinear, nonconvex, large-scale continuous optimization
The Wilkinson Prize is awarded every four years to the entry
that best addresses all phases of the preparation of numerical
software. It is sponsored by Argonne National Laboratory, the
Numerical Algorithms Group, and the National Physical
IPOPT is an object-oriented software library that facilitates
the solution of large-scale continuous optimization problems. It
has been used in a wide range of applications, including automatic
tuning of transistor widths, inverse kinematics of a humanoid
robot, dynamic optimization of chemical processes, portfolio
optimization and risk management, water and wastewater management,
hyperthermia treatment planning, optimal design of masks in wafer
lithography, and the simulation of complex dynamical systems.
IPOPT is available from the COIN-OR open source repository, and
interfaces for modeling languages (AMPL, GAMS), and
for MATLAB, R, Java, and Python are included. In addition, IPOPT
allows the use of several third-party solvers of sparse, symmetric
indefinite linear systems. IPOPT has extensive documentation and a
tutorial that allows users to install and use the package in a
short period of time.
Laird and Waechter are scheduled to receive their awards at the
2011 International Congress on Industrial and Applied Mathematics
in Vancouver, British Columbia, Canada.
