I guess I need to use the character codes for the operators I need but is there an easy way to find these out (I don't think it matters was character encoding standard I use) Thank you loads!

Temporal Logic in Information Systems November 1997. viii+42 pp. Full version to appear in: Logics for Database and Information Systems, Chomicki and Saake (eds.), Kluwer Academic Publishers, 1998. Abstract: Temporal logic is obtained by adding temporal connectives to a logic language. Explicit references to time are hidden inside the temporal connectives. Different variants of temporal logic use different sets of such connectives. In this chapter, we survey the fundamental varieties of temporal logic and describe their applications in information systems. Several features of temporal logic make it especially attractive as a query and integrity constraint language for temporal databases. First, because the references to time are hidden, queries and integrity constraints are formulated in an abstract, representation-independent way. Second, temporal logic is amenable to efficient implementation. Temporal logic queries can be translated to an algebraic language. Temporal logic constraints can be efficiently enforced using auxiliary stored information. More general languages, with explicit references to time, do not share these properties. Recent research has proposed various implementation techniques to make temporal logic practically useful in database applications. Also, the relationships between different varieties of temporal logic and between temporal logic and other temporal languages have been clarified. We report on these developments and outline some of the remaining open research problems.

Interval Temporal Logic Antonio Cau and Ben Moszkowski Software Technology Research Laboratory March 26, 2010 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

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 1960s. Subsequently it has been developed further by computer scientists , notably Amir Pnueli , and logician s. Although Aristotle 's logic is almost entirely concerned with the theory of the categorical syllogism , there are passages in his work that are now seen as anticipations of temporal logic, and may imply an early, partially-developed form of first-order temporal modal binary logic. The first formal system of temporal modal logic was founded by

EST Home Page Efficient Symbolic Tools package (EST) is a tool for the formal verification of systems EST distinguishes itself as a small and portable package with a readable source code in C and well implemented algorithms. EST runs on many different computers with different operating systems, including GNU/Linux, MS Windows, and Solaris. EST is a collection of symbolic algorithms based on binary decision diagrams (BDDs). Curently, it supports only our own BDD package called Biddy , but one day it could support other BDD packages , too. EST itself provides libraries of functions, which you can use in your own main program. Or, you can try our simple Tcl/Tk GUI called My Interface , from which you can access all the features. EST project has started in 1992. In 1999, we devided it into two branches called EST 1st Edition and EST 2nd Edition . Please, follow the given links to obtain source and binary releases. EST is a free software . We can show you every single line of code and we will explain you the meaning of all used constructs if you ask for that. However, it is a sort of academic research software. Some tricks are used, which are not clear to anyone except the author. Thus, do not hesitate to ask us any question you may have about EST. Latest stable sources est-1ed-1-5-2-source.zip

Starlog programs consist of 2 components a set of timed facts, a set of temporal logic rules. Somewhat like Prolog. http://www.cs.waikato.ac.nz/Research/starlog/index.html

A new Logic Programming Language The Starlog Project What is Starlog? Motivation Starlog Concepts Examples ... Department Home !!!STOP PRESS!!! As a follow-on to the Starlog project, we are now developing a new language, called JStar, that shares many of the advantages of Starlog, but is designed to be efficiently implemented on parallel computers. See the JStar Web Page for more details. What is Starlog? Starlog is a pure-logic programming language designed to overcome some of the problems inherient in traditional approaches to logic programming. As a result, Starlog is designed to be a general purpose programming language, and is particularly useful for simulation, and for modelling reactive systems. Although most logic programming languages (e.g. Prolog) are query driven (i.e. are evaluated "top-down"), Starlog programs are evaluated "bottom-up". That is, as a Starlog program executes, it builds a model of all the true facts that can be derived from rules in the program. The evaluation of Starlog programs is controlled using a stratification order. Motivation Traditionally, logic programming languages have never been able to compete with the popularity of other language paradigms. We attribute this to:

My main foci these days include CSPs (constraint satisfaction problems), planning, SAT (satisfiability), Bayesian Inference, and Constraint Optimization Problems. I am interested in developing algorithms for these problems that can achieve better performance by taking advantage of domain specific knowledge or structure. This can sometimes entail developing formalisms for representing such knowledge. For example, F. Kabanza and I developed an approach whereby extra domain specific knowledge can be represented declaratively and used to solve planning problems. Our approach can obtain orders of magnitude increases in performance from very simple domain knowledge. The TLPlan planning system, developed with M. Ady, utilized this approach to planning and demonstrated its effectiveness by winning the AIPS2002

These are for instance as well wont to refer to tense logic, a particular modal logic-based technique of temporal logic introduced by Arthur Prior in the . Afterward it has been developed farther by computer scientists, notably Amir Pnueli, and logicians. Temporal logic was foremost exposed within depth by Aristotle , whose writings are filled sustaining the unprocessed form of number one choose temporal average binary logic. Any logic which utilizes a existential quantifier or the universal quantifier is said to be the first order logic. Any logic which views instance as a sequence of states occurs as temporal logic, and any logic which utilizes simply 2 truth values is a binary logic. Computational tree logic (CTL), Linear temporal logic (LTL) and Interval temporal logic (ITL) are examples of temporal logics.
