Boolean Valued Models and Incomplete Specifications
Logic programming has favored universal Horn theories for several reasons. An advantage of consistent universal Horn theories, compared with arbitrary consistent theories, is the fact that they possess a “typical” model-the least Herbrand model. More precisely, in order to verify that a sentence of the form 3 X, . . . 3 x, A, where A is a conjunction of atomic formulas (i.e. positive literals),...
متن کاملBoolean-valued Term Models
We construct Boolean-valued term models and describe their universal properties. The underlying set of these models consists of the terms of the underlying language, while formulae are interpreted in the Lindenbaum-Tarski algebra of open formulae. Subspaces of the Stone space of the Lindenbaum-Tarski algebra of open formulae are shown to be homeomorphic to spaces of enumerated models models equ...
متن کاملBoolean-Valued Models and Forcing
This introduction to forcing is based on Chapters 5–6 in T. J. Jech’s book The Axiom of Choice and is written primarily for the Fraenkel-Mostowski Models reading group. Forcing is introduced via Boolean-valued models and generic extensions, and these techniques are used to prove the independence of the axiom of choice of ZF. This is then related back to the theory of FM models. Please inform me...
متن کاملNon-Count Symmetries in Boolean & Multi-Valued Prob. Graphical Models
Lifted inference algorithms commonly exploit symmetries in a probabilistic graphical model (PGM) for efficient inference. However, existing algorithms for Boolean-valued domains can identify only those pairs of states as symmetric, in which the number of ones and zeros match exactly (count symmetries). Moreover, algorithms for lifted inference in multi-valued domains also compute a multi-valued...
متن کاملPseudo-Boolean valued prolog
Logic programming has generally been developed in a Classical two-valued setting; there are no “degrees of truth”. What we propose here is the introduction of more general spaces of truth values, reading truth values as “evidence factors”. Then conventional logic programming may be seen as the special case in which only total evidence is acceptable, and so the space of evidences degenerates to ...
