Around line 2612 of slsqp.c, we have
if (nlopt_stop_ftol(stop, fcur, fprev))
ret = NLOPT_FTOL_REACHED;
else if (nlopt_stop_x(stop, xcur, xprev))
ret = NLOPT_XTOL_REACHED;
nlopt_stop_ftol doesn't take the quantity (infeasibility -
infeasibility_cur) into account.
I have a problem where the fit moves to 0.1 and then slsqp needs a
number of major iterations to reduce the inequality constraint from
20000-ish back toward 0.
I guess I should always use an xtol family stopping criterion instead of
ftol when I have constraints?
