Unification is an implementation of logical first-order unification.
A first-order unification procedure unify is given by this library. It can be applied on two terms of type Termtype that are also given by the library.
The solution of a unification problem is a substitution, that is, a mapping assigning a symbolic value to each variable of the problem's expressions.
The unification procedure reports unsolvability for a given problem or computes the complete and minimal substitution set containing the most general unifier. This is a set covering all solutions containing no redundant members.
import "package:tailcalls/tailcalls.dart"; import "package:unification/unification.dart"; var test = unify( new List() ..add( new Tupl( new Term("b0", [new Term("b1", ),new Term("b2", )]), new Term("b0", [new Term("b1", ),new Term("b2", )]), ), ), ).result(); var mgu = test; print(mgu.toString());
