Computing in Unpredictable Environments: Semantics, Reduction Strategies, and Program Transformations. An Intuitionistic Predicate Logic Theorem Prover.
Predicate transformer semantics were introduced by Edsger Dijkstra in his seminal paper "Guarded commands, nondeterminacy and formal derivation of programs". They define the semantics of an imperative programming paradigm by assigning to each statement in this language a corresponding predicate transformer: a total function between two predicates on the state space of the statement. In this sense, predicate transformer semantics are a kind of denotational semantics. Actually, in
It covers propositional and predicate logic with and without identity. It includes an account of the semantics of these languages including definitions of truth and Syllabus: translation to propositional and predicate logic. Deduction in propositional logic - resolution, natural deduction, semantic tableaux, axiom systems. tional subject-predicate logic—the logic that comes so naturally to speak- sult hold also in truly dynamic contexts, where the appropriate semantics is not.

F=favour D=be a dog P=be a park (∀x) (Ǝy) Dx & Py > Fx,y. H=hire M=be a manager E=be an employee (Ǝx) (∀y) Mx & Ey >Hx,y . My attempt is: All dogs favor to be at least in one park.
Relative to the semantics of propositional logic, there are two main sources of complexity. (i) First, in predicate logic atomic formulas are treated as compound ex- pressions, whereas in propositional logic they were unanalyzed primi- tives. What does this mean?
Relative to the semantics of propositional logic, there are two main sources of complexity. (i) First, in predicate logic atomic formulas are treated as compound ex- pressions, whereas in propositional logic they were unanalyzed primi- tives. What does this mean? Semantics for Classical Predicate Logic (Part I)∗ Hans Halvorson Formal logic begins with the assumption that the validity of an argu-ment depends only on its logical form, and not on its content.
Semantics for Predicate Logic: Part I Spring 2004 1 Interpretations A sentence of a formal language (e.g., the propositional calculus, or the predicate calculus) is neither true nor false. By definition, an interpretation ofasentenceofaformallanguageisaspecificationofenoughinformation to determine whether that sentence is true or false.
Terms with variables: x, f(x). Predicate logic’s formulas are always true or false with respect to a structure.
The semantics of Predicate Logic does two things. It assigns a meaning to the individuals, predicates, and variables in the syntax. It also systematically determines the meaning of a proposition from the meaning of its constituent parts and the order in which those parts combine (Principle of Compositionality). For the
The semantics of predicate logic Readings: Section 2.4, 2.5, 2.6. In this module, we will precisely define the semantic interpretation of formulas in our predicate logic.

However, it is known that completeness with respect to models is as easy to show as in predicate logic but that if the language contains equality, di»erent semantics have to be chosen for di»erent theories/logics of identity (cf. e.g. [7]).

With predicate logic, we're much closer to the semantics of real languages than just with the tools we had before, with sentential logic. Extra Materials: In this
