The series of International Conferences on Logic for Programming, Artificial Intelligence and Reasoning (LPAR) is a forum where, year after year, some of the most renowned researchers in the areas of automated reasoning, computational logic, programming languages and their applications come to present cutting-edge results, to discuss advances in these fields, and to exchange ideas in a scientifically emerging part of the world. The 2008 edition will be held in Doha, Qatar, on the premises of the Qatar campus of Carnegie Mellon University.

Logic is a fundamental organizing principle in nearly all areas in Computer Science. It runs a multifaceted gamut from the foundational to the applied. At one extreme, it underlies computability and complexity theory and the formal semantics of programming languages. At the other, it drives billions of gates every day in the digital circuits of processors of all kinds. Logic is in itself a powerful programming paradigm but it is also the quintessential specification language for anything ranging from real-time critical systems to networked infrastructures. It is logical techniques that link implementation and specification through formal methods such as automated theorem proving and model checking. Logic is also the stuff of knowledge representation and artificial intelligence. Because of its ubiquity, logic has acquired a central role in Computer Science education.

New results in the fields of computational logic and applications are welcome. Also welcome are more exploratory presentations, which may examine open questions and raise fundamental concerns about existing theories and practices. Topics of interest include, but are not limited to:

- Automated reasoning
- Interactive theorem proving
- Implementations of logic
- Proof assistants
- Program and system verification
- Model checking
- Rewriting and unification
- Logic programming
- Constraint programming
- Logic and databases
- Modal and temporal logics
- Proof-carrying code
- Translation validation
- Logic for the semantic web
- Foundations of security
- Description logics
- Non-monotonic reasoning
- Specification using logics
- Logic in artificial intelligence
- Lambda calculus
- Constructive logic and type theory
- Computional interpretations of logic
- Logical foundations of programming
- Logical aspects of concurrency
- Logic and computational complexity
- Knowledge representation and reasoning
- Reasoning about actions
- Proof planning
- Effectively presented structures
- Logic of distributed systems

Invited Speakers
It has been a tradition of LPAR to invite some of the most influential researchers in the focus areas to discuss their work and their vision for their fields. We are honored that the following members of the community have accepted this invitation.

Edmund Clarke, Carnegie Mellon University (USA)
Amir Pnueli, New York University (USA)
Michael Backes, Saarland University and MPI-SWS (Germany)
Thomas Eiter, Technical University of Vienna (Austria)

Submission Instructions
Submissions must not substantially overlap papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Papers should be submitted in Postscript or Portable Document Format (PDF); papers submitted in a proprietary word processor format such as Microsoft Word cannot be considered. Submissions can be of two types:

Regular papers are meant to describe solid new research results. They can be up to 15 pages long in LNCS style, including figures, bibliography and appendices.
Experimental and tool papers are intended to describe implementations of systems, to report experiments with implemented systems, or to compare implemented systems. They can be at most 8 pages long in the LNCS style.
Both types of papers can be electronically submitted by visiting http://www.easychair.org/conferences/?conf=lpar2008. Prospective authors are required to register a title and an abstract a week before the paper submission deadline (see below).

As with the previous editions, the proceedings of LPAR'08 will be published in Springer-Verlag's Lecture Notes in Computer Science series. They will be available at the conference.

In keeping with the tradition of LPAR, researchers and practioners are encouraged to report on interesting work in progress by submitting abstracts of up to 5 LNCS pages, to be selected for a short-paper session. These abstracts will not be printed in the proceedings of LPAR'08 and they have a separate submission deadline (see below).

Participation
Authors of accepted papers are required to ensure that at least one of them will be present at the conference. Papers that do not adhere to this policy will be removed from the proceedings.
