PADL 2012: Call for Participation

14th International Symposium on
Practical Aspects of Declarative Languages (PADL 2012)

Co-located with ACM POPL’12

You are cordially invited to PADL’12. PADL is a forum for researchers and
practitioners to present original work emphasizing novel applications and
implementation techniques for all forms of declarative concepts, including
functional, logic and constraints. PADL’12 is sponsored by Association for
Logic Programming with cooperation of ACM SIGPLAN and support by Microsoft


To register for PADL’12, please follow the instructions at:

The early registration deadline is December 24, 2011. The registration fee will cover
