pub const POLISH_TIGHTEN: Number = 1e-3;Expand description
A polished point must bring the natural residual to max(tol, POLISH_TIGHTEN · r_old). Not tol alone: a held H side is a row pinned
to zero, which the branch solve satisfies only to its constraint
tolerance, so a correct polish can end at |h| = 3e-8. On the 54
polishes measured (MacMPEC, the OPF and capacity suites) every one reached
1e-8 or below, so this rejects nothing those accepted.
