INTRODUCTION
CL&C'12 is the fourth of a conference series on Classical Logic and Computation. It intends to 
cover all work aiming to explore computational aspects of classical logic and mathematics.  This 
year CL&C will be held as satellite workshop of ICALP'12 in Warwick:
http://www2.warwick.ac.uk/fac/cross_fac/dimap/icalp2012/

CL&C is focused on the interplay between program extraction from classical the exploration of the 
computational content of mathematical and logical principles. The scientific aim of this workshop 
is to bring together researchers from both fields and exchange ideas.

SCOPE OF CL&C
This workshop aims to support a fruitful exchange of ideas between the various lines of research 
on Classical Logic and Computation. Topics of interest include, but are not limited to,

  - version of lambda calculi adapted to represent classical logic;
  - design of programming languages inspired by classical logic;
  - cut-elimination for classical systems;
  - proof representation and proof search for classical logic;
  - translations of classical to intuitionistic proofs;
  - constructive interpretation of non-constructive principles;
  - witness extraction from classical proofs;
  - constructive semantics for classical logic (e.g. game semantics);
  - case studies (for any of the previous points).

SUBMISSION AND PUBLICATION.
This is intended to be an informal workshop. Participants are encouraged to present work in 
progress, overviews of more extensive work, and programmatic / position papers, as well as 
completed projects. We therefore ask for submission both of short abstracts and of longer papers.

All submitted papers will be reviewed to normal standards. The PC recognises two kinds of papers: 
it will distinguish between accepted (full) papers that contain unpublished results not submitted 
elsewhere, and presentations of (short) papers about work in progress. The accepted papers will 
appear in EPTCS.

In order to make a submission:
- Format your file using the LNCS guidelines; there is a 15 page limit.
- Use the submission instructions at

https://www.easychair.org/conferences/?conf=clc2012

A participants' proceedings will be distributed at the workshop.
