MPSGE

MPSGE is not actually a solver but rather is a preprocessor that aids in the formulation and solution of general equilibrium problems and operates as a subsystem to GAMS developed by T. Rutherford at University of Colorado.  MPSGE is a library of function and Jacobian evaluation routines that generate an MCP problem that must be solved with a MCP solver.  MPSGE, while in GAMS also involves a model definition language with alternative syntax and conventions that are unlike that used in the rest of GAMS.  The modeling syntax and conventions are explained in MPSGE.pdf and additional material can be found at http://www.mpsge.org/mainpage/mpsge
