const Interval< Number > &  h = Interval<Number>(0,0) 
) const
inline

Evaluate this contraction over the given assignment.

Returns a list of resulting intervals.

Allows to integrate a relation symbol as follows:

  • Transform relation into an interval (e.g. < 0 to = (-oo, 0))
  • Transform constraint to equality (e.g. p*x - q < 0 to p*x - q = h)
  • Evaluate with respect to interval h (e.g. x = (q + h) / p)
