pyomo.contrib.fbbt.interval.ineq(xl, xu, yl, yu, feasibility_tol)

Compute the “bounds” on an InequalityExpression

Note this is not performing interval arithmetic: we are calculating the “bounds” on a RelationalExpression (whose domain is {True, False}). Therefore we are determining if x can be less than y, x can not be less than y, or both.
