TOPIC AND OBJECTIVE:
Methods for decision problems of a logic are of vital importance for both the theoretical relevance 
and practical impact of a logic. Different logics require different decision procedures. 
Nevertheless, certain methodologies like terminating semantic tableaux, automata, games, SAT/SMT 
methods, resolution, reductions, etc. have proved to be successful in providing decidability 
results for several, even quite different logics.
   Perception of some methodology being better than others has grown within certain communities, 
for example regarding automata-based techniques in automatic verification or tableau-based 
techniques in knowledge representation. Such perception, however, is often not based on systematic 
comparative analysis. Sometimes, different methodologies also turn out to do or even be the same 
in certain cases. Yet, few formal technical results to that effect are known, and the scientific 
discussions on the pros and cons, and similarities and differences between different methodologies
have been rather sporadic so far.
   The purpose of this workshop is to provide an expert forum for such discussion, to provoke and 
foster discussion between communities, and to stimulate further research on that topic. It is a 
follow-up to the CLoDeM'2010 workshop held within FLOC 2010 in Edinburgh in July 2010, affiliated 
with LICS and IJCAR.
   The workshop welcomes contributions on comparisons between different methods, exhibiting 
differences or similarities, in theory or in practice, in general or with respect to a certain logic.


SUBMISSIONS:
Submissions should be in the form of extended abstracts of at most 15
A4 pages in PDF format using Springer LNCS style or an equivalent format.
Submissions may be based on new and original, or on already published or submitted work, but they 
should address the topic of the workshop. 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. At least one author of each submission that is accepted for the workshop must register 
for and attend the workshop in order to present the paper.

Submissions deadline:                April  2, 2012
