Linear temporal logic From Wikipedia, the free encyclopedia Jump to: navigation search Linear temporal logic (LTL) is a modal temporal logic with modalities referring to time. In LTL, one can encode formulae about the future of paths such as that a condition will eventually be true, that a condition will be true until another fact becomes true, etc. Contents History Syntax Semantics Equivalences ... edit History LTL was first proposed for the verification of computer programs by Amir Pnueli in 1977. edit Syntax LTL is built up from a set of propositional variables , the usual logic connectives and the following temporal modal operators X for next ( N is used synonymously) G for always ( g lobally) F for eventually (in the f uture) U for until R for release The first three operators are unary, so that X is a well-formed formula whenever is a well-formed formula. The last two operators are binary, so that U is a well-formed formula whenever and are well-formed formulas. edit Semantics An LTL formula can be evaluated over an infinite sequence of truth evaluations and a position on that path. An LTL formula is satisfied by a path if and only if it is satisfied for position on that path. The semantics for the modal operators is given as follows.

Tuesday 2 November 2010 Home Company Partners References ... Psl Temporal Logic The temporal operators of the foundation language provide syntactic sugaring on top of the LTL operators. These temporal operators include always never next until and before , amongst others. The meaning of these operators is quite intuitive, but there are a few surprises. The always operator holds if its operand holds in every single cycle, whilst the never operator holds if its operand fails to hold in every single cycle. The next operator holds if its operand holds in the cycle that immediately follows. Hence the assertion means that whenever the HDL signal req is true, the HDL signal grant must be true in the following cycle. The meaning of a cycle will typically be specified either by defining a default clock or by including the clocking operator within the property. Note that when req is true, this assertion says nothing about the value of grant in any cycle other than the immediately following cycle. Also, it says nothing about the value of grant when req is false. It only says that whenever

Temporal logic - Definition 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 Temporal logic was first studied in depth by Aristotle , and his 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. The three basic temporal operators are: Always, sometimes, and never. Computational tree logic (CTL)

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.

TLA (the Temporal Logic of Actions) is a logic for specifying and reasoning about concurrent and reactive systems. It is the basis for TLA+, a complete specification language. This Web page will be updated to reflect new work on TLA. I hope that all work on TLA and TLA tools will be accessible from here.

It should allow you to understand TLA specifications. A Summary of TLA+ This is a 7-page "cheat sheet" that briefly describes all the constructs and built-in operators of TLA+ and the operators defined in the common standard modules, and that lists the user-definable operator symbols and the ascii representations of symbols.

Front Desk Browse the Stacks Temporal Logic Case Study 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. View Complete Report PDF [135 KB] Author William G.

19. TIME International Symposium Series The annual International Workshop on Temporal Representation and Reasoning covers temporal representation and reasoning, including temporal logic. http://www.cs.uregina.ca/~temporal/

TIME International Symposium Series You have reached the old web site for the TIME International Symposium Series. The new web site is at http://time.dico.unimi.it The TIME International Symposium Series began in 1994. The first six annual meetings were held as workshops in conjunction with the FLAIRS (Florida Artificial Intelligence Research Society) annual conference. As the workshop has grown, the participants decided to hold the annual meeting as an independent event. Since its inception, the purpose of this symposium series has been to bring together active researchers in the area of temporal representation and reasoning in Artificial Intelligence. Through paper presentations and discussions, the participants will exchange, compare, and contrast results in the area. Over the years, participation of researchers from areas outside of mainstream AI (especially the database community) has grown. For this reason, beginning with TIME-2001, we have opened the meeting to active researchers in temporal (including temporal-spatial) representation and reasoning from all areas. Additionally, the annual meeting has matured and the format has evolved to the point where it is more appropriately identified as a symposium rather than a workshop. Also, beginning with TIME-2001, we have adopted a track format for the symposium. For information about the current or previous meetings, follow the appropriate link below.
