Abstract
Proximity relations are fuzzy binary relations satisfying reflexivity and symmetry properties. Tolerance, which is a reflexive and symmetric (and not necessarily transitive) relation, can be also seen as a crisp version of proximity. We discuss two fundamental symbolic computation problems for proximity and tolerance relations: matching and anti-unification, present algorithms for solving them, and study properties of those algorithms.
