BndMPCC: Bound-Constrained Mathematical Programs with Complementarity Constraints

A small collection of MPCCs that have only simple bounds or complementarity constraints between variables.

Bound-Constrained Quadratic Programs with Complementarity Constraints

Randomly generated QPCCs with bound constraints in AMPL format.

Bound-Constrained Nonlinear Programs with Complementarity Constraints

Problem instances generated from unconstrained nonlinear optimization problems by adding bounds and two types of complementarity constraint (verions 0 and 1).

Each function can be run with an adjustable number of variables. NL-files for a subset of instances are here: (instances with NLP correspond to problems in which the complementarity constraint was replaced by a nonlinear inequality constraint).
