Temporal logic From Wikipedia, the free encyclopedia Jump to: navigation search In logic , the term temporal logic is used to describe any system of rules and symbolism for representing, and reasoning about, propositions qualified in terms of time . It is sometimes also used to refer to tense logic , a particular modal logic -based system of temporal logic introduced by Arthur Prior in the . Subsequently it has been developed further by computer scientists , notably Amir Pnueli , and logicians Temporal logic was first studied in depth by Aristotle , whose writings are filled with a crude form of first-order temporal modal binary logic. Any logic which uses the existential quantifier or the universal quantifier is said to be a first-order logic . Any logic which views time as a sequence of states is a temporal logic, and any logic which uses only two truth values is a binary logic Consider the statement: "I am hungry." Though its meaning is constant in time, the truth value of the statement can vary in time. Sometimes the statement is true, and sometimes the statement is false, but the statement is never true and false simultaneously. In a temporal logic, statements can have a truth value which can vary in time. Contrast this with an atemporal logic, which can only handle statements whose truth value is constant in time. In a temporal logic we can then express statements like "I am always hungry", "I will

5. Alur/Henzinger/Kupferman: Alternating-time Temporal Logic Temporal logic comes in two varieties lineartime temporal logic assumes implicit universal quantification over all paths that are generated by system http://www.eecs.berkeley.edu/~tah/Publications/alternating-time_temporal_logic.h

Alternating-time Temporal Logic Rajeev Alur, Thomas A. Henzinger , and Orna Kupferman Temporal logic comes in two varieties: linear-time temporal logic assumes implicit universal quantification over all paths that are generated by system moves; branching-time temporal logic allows explicit existential and universal quantification over all paths. We introduce a third, more general variety of temporal logic: alternating-time temporal logic offers selective quantification over those paths that are possible outcomes of games, such as the game in which the system and the environment alternate moves. While linear-time and branching-time logics are natural specification languages for closed systems, alternating-time logics are natural specification languages for open systems. For example, by preceding the temporal operator "eventually" with a selective path quantifier, we can specify that in the game between the system and the environment, the system has a strategy to reach a certain state. The problems of receptiveness, realizability, and controllability can be formulated as model-checking problems for alternating-time formulas. Depending on whether or not we admit arbitrary nesting of selective path quantifiers and temporal operators, we obtain the two alternating-time temporal logics ATL and ATL*. ATL and ATL* are interpreted over concurrent game structures Journal of the ACM 49:672-713, 2002. Preliminary versions appeared in the

Home Site Map Pathways to Western Philosophy Philosophical Logic and Philosophy of Logic INTRODUCTORY READINGS Priest Graham. Logic: a very short introduction . Oxford: Oxford University Press 2000. From the Preface: "This book is an introduction to logic, as contemporary logicians now understand the subject. It does not attempt to be a textbook, however. There are numerous such books currently available. The point of this one is to explore the roots of logic, which sink deep into philosophy. Some format logic will be explained along the way. In each of the main chapters, I start by taking up some particular philosophical problem or logical puzzle. I then explain one approach to it. Often this is a fairly standard one; but in some of the areas there is no standard answer: logicians still disagree. In such cases, I have just chosen one that is interesting. Nearly all the approaches, whether standard or not, may be challenged. I finish each chapter with some problems for the approach that I have explained. Sometimes these problems are standard; sometimes they are not. Sometimes they may have easy answers; sometimes they may not. The aim is to challenge you to figure out what you make of the matter. Modern logic is a highly mathematical subject. I have tried to write the material in such a way as to avoid nearly all mathematics. The most that is required is a little high-school algebra in the last few chapters. It is true that you will need the determination to master some symbolism that may be new to you; but this is a lot less than is required to have a basic grasp of any new language. And the perspicuity that the symbolism gives to difficult questions makes any trouble one may have in mastering it well worth it. One warning, though: reading a book on logic or philosophy is not like reading a novel. There will be times when you will have to read slowly and carefully. Sometimes you may have to stop and think about things; and you should be prepared to go back and reread a paragraph if necessary.

Applications of Temporal Logic include its use as a formalism for clarifying philosophical issues about time, as a framework within which to define the semantics of temporal expressions in natural language, as a language for encoding temporal knowledge in artificial intelligence, and as a tool for handling the temporal aspects of the execution of computer programs. 1.

Technical Report CMU/SEI-89-TR-024 PDF File PostScript File This report is a case study applying temporal logic to specify the operation of a bank of identical elevators servicing a number of floors in a building. The goal of the study was to understand the application of temporal logic in a problem domain that is appropriate for the method, and to determine some of the strengths and weaknesses of temporal logic in this domain. The case study uses a finite state machine language to build a model of the system specification, and verifies that the temporal logic specifications are consistent using this model. The specification aspires to be complete, consistent, and unambiguous. Privacy Statement

Interval Temporal Logic Antonio Cau Ben Moszkowski and Hussein Zedan Software Technology Research Laboratory January 15, 2008 Pdf version of the ITL home page ITL-course: A not so short introduction to ITL Abstract Interval Temporal Logic (ITL) is a flexible notation for both propositional and first-order reasoning about periods of time found in descriptions of hardware and software systems. Unlike most temporal logics, ITL can handle both sequential and parallel composition and offers powerful and extensible specification and proof techniques for reasoning about properties involving safety, liveness and projected time . Timing constraints are expressible and furthermore most imperative programming constructs can be viewed as formulas in a slightly modified version of ITL . Tempura provides an executable framework for developing and experimenting with suitable ITL specifications. In addition, ITL and its mature executable subset Tempura have been extensively used to specify the properties of real-time systems where the primitive circuits can directly be represented by a set of simple temporal formulae. In addition, various researchers have applied Tempura

For this we need a multi-modal logic with the following -operators F A A holds always in the future P A A holds always in the past A A A holds always and the corresponding -operators: A holds somewhere in the future A holds somewhere in the past A holds somewhere The semantics is then given as before, by giving constraints for the three reachability relations or by giving appropriate axioms, e.g. : Transitivity; an analog axiom hods for the two other -operators. : if we go from a time point t in the future t , we can go back in the past to the time point where A was true. : connection of past with future. In addition there are many other aspects of temporal logics. E.g. one can distinguish between left- and rightlinear structures or between dense and discrete time structures.
