A package which implements various systems of n valuedlogic.

Project description

MVL (many valued logic)

MVL (many valued logic) is a python package which implements different logic systems that use more than 2 values.

What logic systems are implemented?

The following 3 valued logic systems are supported by MVL:

  • Bochvar
  • Kleene
  • Priest

The following n valued logic systems are supported by MVL:

  • Łukasiewicz

The following systems are planned for future support:

  • Gödel MVL
  • Belnap
  • Product logic
  • Post logic


Using MVL is designed to integrate with existing python infrastructure as much as possible. Example usages of kleene and lukasiewicz logic are given below.

>>> from mvl import kleene as k
>>> k.t
>>> k.and_(k.t, k.u)
>>> k.or_(k.u, k.u)
>>> k.implies(k.u, k.t)
>>> k.implies(k.u, k.u)
>>> k.implies(k.f, k.u)

>>> from mvl.lukasiewicz import *
>>> ls = LogicSystem(5, LukasiewiczLogicValue)
>>> ls.values
[LukasiewiczLogicValue(0.0), LukasiewiczLogicValue(0.25), LukasiewiczLogicValue(0.5), LukasiewiczLogicValue(0.75), LukasiewiczLogicValue(1.0)]
>>> t = ls.values[4]
>>> bool(t)
>>> bool(ls.values[3])
