This new perspective, combined with much improved insights into the semantically defined discourse dependency of natural language sentences, leads to a novel and more functionally oriented approach to logic and
(读到这里的时候我真的止不住的,天啊啊啊啊啊太好玩了太妙了。因为,我从没想到之前学过的predicate logic,会结合图论,出现在P VS NP的章节里面。所以,为了分享最后这段结论(这碟醋)包了整盘饺子,也就是这篇文章ww) (知识点大部分都取自于Introduction to the Theory of Computation. Sipser)超好玩的一本...
The meaning of PROPOSITIONAL CALCULUS is the branch of symbolic logic that uses symbols for unanalyzed propositions and logical connectives only —called also sentential calculus.
Logic: study of entailment relations Using Logic# No universal language / semantics No universal reasoning scheme Start with first-order predicate calculus(FOL) Why do we need formal Knowledge Representation?# Natural languages exhibit ambiguity ambiguity make it difficult to make any inferences Syntax ...
Truth in First-order Logic Sentences are true with respect to a model and an interpretation Model contains 1 objects (domain elements) and relations among them Interpretation specifies referents for Constant symbols -> objects Predicate symbols -> relations Function symbols -> functional relations ...
We give a sequential reduction technique for transforming a formula of the pure predicate calculus to a sequence of 'increasingly accurate' propositional logic 'approximations' to the predicate formula. At each stage of approximation, one of the following three cases occurs: (1) the approximation sh...

A predicate language over a propositional language S is a couple qS = ( S , q ) where q is the signature of qS , i.e. the function which divides descriptive terms D ( q ) of qS into syntactical categories. All predicate languages involve the sets V f and V b of free and bound ...
