alpha_for_y_tol:

Tolerance for switching to full equality multiplier steps. $\;$
This is only relevant if "alpha_for_y" is chosen "primal-and-full" or "dual-and-full". The step size for the equality constraint multipliers is taken to be one if the max-norm of the primal step is less than this tolerance. The valid range for this real option is $0 \le {\tt alpha\_for\_y\_tol } < {\tt +inf}$ and its default value is $10$.
