Unification
A library providing implementations of first-order logical unification for dart and flutter.
Getting started
Add the dependency to your pubspec.yaml file:
dependencies:
unification: #latest versionAdd the import statement to your source files:
import 'package:unification/unification.dart';Or, give it a try and run the example:
dart ./example/main.dart Modify the example to test more less simple tasks!
Example:
import "package:unification/unification.dart";
//
Termtype<String, Id> term1 = Term(Id(1, 1), [
Var(
Id(1, 2),
),
Var(
Id(1, 2),
),
]);
//
Termtype<String, Id> term2 = Term(Id(2, 1), [
Var(
Id(2, 2),
),
Term(Id(2, 3), [
Var(
Id(2, 2),
),
]),
]);
print('Occurs Check: Circularity.');
UnificationR<String, Id> u = UnificationR<String, Id>();
var mgu = u.unify(term1, term2, []);
var unifiedTerm1 = u.subsitute(mgu, term1);
var unifiedTerm2 = u.subsitute(mgu, term2);
print('mgu > ' + mgu.toString());
print('term 1 > ' + unifiedTerm1.toString());
print('term 2 > ' + unifiedTerm2.toString());Read more about unification in logic on Wikipedia.
