AutoTab'09: LAST CALL AND EXTENDED DEADLINE FOR SUBMISSIONS

AutoTab'09 is a TABLEAUX'2009 workshop on "Tableaux versus automata as logical decision methods", to be held in Oslo on July 6, 2009.    					                     

TOPIC AND OBJECTIVE:
Terminating semantic tableaux have served for a long time as one of the practically most efficient types of decision procedures for a wide range of logical systems. On the other hand, automata-based methods for testing satisfiability and model checking for various modal and temporal logics of computations have gained very wide recognition and popularity over the past two decades, because they provide uniform, elegant, and often optimal decision procedures. Furthermore, a number of increasingly efficient automata-based tools have been implemented and used for academic and industrial purposes, and there seem to be a growing perception amongst the formal verification community that these tools are superior and preferable to the tableau-based tools. That perception, however, is not based on systematic comparative analysis, and some practical experience with well-designed tableau-based tools suggest that such perception can sometimes be misleading. Moreover, various optimization techniques, such as on-the-fly methods, draw automata-based algorithms very close to tableau-like procedures, thus strongly suggesting that tableaux and automata are closely related formalisms for deciding logical satisfiability. Yet, few formal technical results to that effect are known, and the scientific discussion on the pros and cons, similarities and differences, comparisons of applicability, efficiency, and performance between tableaux and automata has so far been rather sporadic.

The purpose of the workshop is to provide an expert forum for such discussion, to provoke and foster debate between the automata and tableaux communities, and to stimulate further research on the topic.

IMPORTANT DATES:
Submissions EXTENDED DEADLINE:  May 11, 2009 		
Notification deadline: May 30, 2009
Preliminary programme: June 5, 2009
Final programme:       June 12, 2009
Workshop:              July 6, 2009

SUBMISSIONS:
Submissions for workshop talks are invited by means of extended abstracts within 5 A4 pages in PDF or PS format, using Springer LNCS style. Submissions may be based on new and original, or on already published or submitted work, but they should address the topic of the workshop. 

Submissions can be uploaded through the EasyChair submission site: https://www.easychair.org/login.cgi?conf=autotab09

The abstracts of the workshop talks will be included in informal proceedings. No formal proceedings are currently planned, but if the workshop attracts sufficiently many good and original contributions, a journal special issue will be organized after the event.
