compl_inf_tol:

Desired threshold for the complementarity conditions. $\;$
Absolute tolerance on the complementarity. Successful termination requires that the max-norm of the (unscaled) complementarity is less than this threshold. The valid range for this real option is $0 < {\tt compl\_inf\_tol } < {\tt +inf}$ and its default value is $0.0001$ .
