constr_mult_reset_threshold:

Threshold for resetting equality and inequality multipliers after restoration phase. $\;$
After returning from the restoration phase, the constraint multipliers are recomputed by a least square estimate. This option triggers when those least-square estimates should be ignored. The valid range for this real option is $0 \le {\tt constr\_mult\_reset\_threshold } < {\tt +inf}$ and its default value is 0.
