recalc_y:

Tells the algorithm to recalculate the equality and inequality multipliers as least square estimates. $\;$
This asks the algorithm to recompute the multipliers, whenever the current infeasibility is less than recalc_y_feas_tol. Choosing yes might be helpful in the quasi-Newton option. However, each recalculation requires an extra factorization of the linear system. If a limited memory quasi-Newton option is chosen, this is used by default. The default value for this string option is "no".
Possible values:

• no: use the Newton step to update the multipliers
• yes: use least-square multiplier estimates
