eq

(function from pyomo.contrib.fbbt.interval)

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

Compute the “bounds” on an EqualityExpression

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 equal to y, x can not be equal to y, or both.
