The Wilkinson Prize for Numerical Software

James Wilkinson

In honour of the outstanding contributions of James Hardy Wilkinson to the field of numerical software, Argonne National Laboratory, the National Physical Laboratory, and the Numerical Algorithms Group award a prize of US $3000 to an outstanding piece of numerical software every four years.

The Wilkinson Prize 2011

The Wilkinson Prize 2011 was awarded to Andreas Waechter and Carl D. Laird for their Ipopt software at ICIAM, July 2011.

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.
