unification
The generalisation of pattern matching that is
the logic programming equivalent of instantiation in
logic. When two terms are to be unified, they are
compared. If they are both constants then the result of
unification is success if they are equal else failure. If one
is a variable then it is bound to the other, which may be any
term (which satisfies an "occurs check"), and the
unification succeeds. If both terms are structures then each
pair of sub-terms is unified recursively and the unification
succeeds if all the sub-terms unify.
The result of unification is either failure or success with a
set of variable bindings, known as a "unifier". There may
be many such unifiers for any pair of terms but there will be
at most one "most general unifier", other unifiers simply
add extra bindings for sub-terms which are variables in the
original terms.
