pub const BOUND_TOLERANCE: f64 = 1e-6;Expand description
Relative tolerance of the objective-bound rules of Outcome::check:
two objective values a and b agree, and a dual bound may lie beyond
the primal bound, by at most BOUND_TOLERANCE * max(1, |a|, |b|). Workers
with tighter tolerances decide more strictly on their own and keep a
rejected value in details.
