The Analysis and Synthesis of Logic Translation

AAAI Conferences

In some relative discussions about the conceptual analysis of translation paradox where people Studies about logic translation could be traced back to (Kolmogorov found the following situation paradoxical with an assumption 1925) (Glivenko 1929) (Gentzen 1933) (Gödel of stronger-weaker distinction about the strength of logics (1933). In this chapter, the discussion on Béziau's case of by weakening the condition of some logical constant on the translation paradox provides an easier way for people purpose: given two logics, one is weaker than the other in to understand how it is possible for people to consider the sense of proving everything the former proves, while at a more general and abstract logic by the bivaluation approach.


Interpolable Formulas in Equilibrium Logic and Answer Set Programming

Journal of Artificial Intelligence Research

Interpolation is an important property of classical and many non-classical logics that has been shown to have interesting applications in computer science and AI. Here we study the Interpolation Property for the the non-monotonic system of equilibrium logic, establishing weaker or stronger forms of interpolation depending on the precise interpretation of the inference relation. These results also yield a form of interpolation for ground logic programs under the answer sets semantics. For disjunctive logic programs we also study the property of uniform interpolation that is closely related to the concept of variable forgetting. The first-order version of equilibrium logic has analogous Interpolation properties whenever the collection of equilibrium models is (first-order) definable. Since this is the case for so-called safe programs and theories, it applies to the usual situations that arise in practical answer set programming.


Rapper Logic reportedly splits from wife of 2 years

FOX News

Another couple has called it quits. Rapper Logic and his wife, Jessica Andrea, have reportedly split after two years of marriage, according to multiple reports. The couple tied the knot in October of 2015 after dating for two years. Though, fans quickly noticed that Andrea no longer follows the "1-800-273-8255" rapper on Instagram. ET has reached out to Logic's rep for comment.
