slack_bound_push:

Desired minimum absolute distance from the initial slack to bound. $\;$
Determines how much the initial slack variables might have to be modified in order to be sufficiently inside the inequality bounds (together with "slack_bound_frac"). (This is kappa_1 in Section 3.6 of implementation paper.) The valid range for this real option is $0 < {\tt slack\_bound\_push } < {\tt +inf}$ and its default value is $0.01$.
