Abstract

The Beale-Orchard-Hays Prize is dedicated to the memory of Martin Beale and William Orchard-Hays, pioneers in computational mathematical programming. The prize is awarded every three years by the Mathematical Programming Society to honor the outstanding paper in the area of computational mathematical programming. This year, the prize was awarded to Steven Dirkse and Michael Ferris for their paper

"The PATH solver: A Non-Monotone Stabilization Scheme for Mixed Complementarity Problems", Optimization Methods and Software, 5:123-156, 1995

The PATH solver is an implementation of a stabilized Newton method for the solution of the Mixed Complementarity Problem. In this talk, we give an overview of complementarity problems, describe how the PATH solver works, and discuss some of the impact that this work has had on the field.
