    • Crash Techniquees for Large-Scale Complementarity Problems 

      Ferris, Michael C.; Dirkse, Steven P. (1995)
      Most Newton-based solver for complementarity problems converge rapidly to a solution once they are close to the solution point and the correct active set has been found. We discuss the design and implementation of crash ...
    • Modeliing Solution Environments for MPEC: GAMS & MATLAB 

      Ferris, Michael C.; Dirkse, Steven P. (1998-01)
      We describe several new tools for modeling MPEC problems that are built around the introduction of an MPEC model type into the GAMS language. We develop subroutines that allow such models to be communicated directly to ...
    • Traffic Modeling and Variational Inequalities using GAMS 

      Ferris, Michael C.; Dirkse, Steven P. (1997-04)
      We describe how several traffic assignment and design problems can be formulated within the GAMS modeling language using newly developed modeling and interface tools. The fundamental problem is user equilibrium, where ...
