2 years ago Perhaps clarify that this must be the case in the non-feasible region?
Interior methods only consider the feasible region. There, g(x) <= 0, so -1/(g(x)) will be non-negative as desired. This really only needs to hold in the feasible region.
I can go ahead and add "in the feasible region" - thanks!
Condition 2 mentions that p_barrier must be nonnegative. Perhaps clarify that this must be the case in the non-feasible region? The inverse barrier function is also positive when all gi<0 and negative when all gi>0, which is not the expected behavior.
