All of the following examples satisfy (# of variables) = (# of complementarity constraints) + (# of equality constraints). As a result, they they give rise to "square" systems that are accepted by the PATH solver. The numbers of variables and constraints sent to PATH (after the presolve phase) is listed in the

Files ending in `.mod` contain complementarity models. Data may
also appear in these files, or may be in separate files ending in
`.dat`. Files ending in `.run` are scripts that solve
the associated problems from various starting points.

Most of these examples have been adapted from GAMS models in MCPLIB.
