The 2011 Wilkinson Prize for Numerical Software will be awarded to
Andreas Waechter (IBM T. J. Watson Research Center) and Carl Laird
(Texas A&M University) for IPOPT, a software library for solving
nonlinear, nonconvex, large-scale continuous optimization problems.
The presentation of the award will take place at the International
Congress on Industrial and Applied Mathematics (ICIAM 2011) in
Vancouver, BC, Canada.
IPOPT is an object-oriented software library that facilitates the
solution of large-scale continuous optimization problems. 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.
IPOPT is available from the COIN-OR open source repository. IPOPT 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.
The Wilkinson Prize is awarded every four years to the entry that best
addresses all phases of the preparation of numerical software, and is
sponsored by Argonne National Laboratory (US), the Numerical
Algorithms Group (UK), and the National Physical Laboratory (UK).

My sincerest congratulations to Andreas and Carl! They have done a tremendous job developing and supporting Ipopt all these years, and it is truly great that such a powerful optimization library has been made available as open source. Andreas and Carl are indeed worthy of this recognition.
ReplyDeleteIn the above announcement, the interfaces maintained in the COIN-OR Ipopt repository are mentioned. I just wanted to point out that there is also a .NET interface to Ipopt, developed by me, available here: http://code.google.com/p/csipopt/ .
The .NET interface can make use of the prebuilt Ipopt binaries, and it supports all functionality that is available in the regular C and Fortran interfaces of Ipopt up to at least version 3.9.2. There are also working examples available in C#, VB.NET and F#.
This knowledge is really great for us but unfortunately this time I am searching for logistics software. So, if anyone knows any information about this then please provides it to me. Thanks.
ReplyDeleteEveryone says business reviews are excessive for SEO. How? Is there any websites where I can go to view charts or studies on this topic?
