required_infeasibility_reduction:

Required reduction of infeasibility before leaving restoration phase. $\;$
The restoration phase algorithm is performed, until a point is found that is acceptable to the filter and the infeasibility has been reduced by at least the fraction given by this option. The valid range for this real option is $0 \le {\tt required\_infeasibility\_reduction } < 1$ and its default value is $0.9$.
