barrier_tol_factor:

Factor for mu in barrier stop test. $\;$
The convergence tolerance for each barrier problem in the monotone mode is the value of the barrier parameter times "barrier_tol_factor". This option is also used in the adaptive mu strategy during the monotone mode. (This is kappa_epsilon in implementation paper). The valid range for this real option is $0 < {\tt barrier\_tol\_factor } < {\tt +inf}$ and its default value is $10$.
