The ACL2 Workshop Series

We hold regular workshops. In 2010, the ACL2 Workshop did a one-time merger with TPHOLs to form the first International Conference on Interactive Theorem Proving (ITP). Such a merger may occur again, but whether or not that happens, the ACL2 community is encouraged to participate in ITP. Other conferences of particular interest to the ACL2 community include CAV (Computer Aided Verification) and FMCAD (Formal Methods in Computer Aided Design).

ACL2 Workshop 2015: October 1-2, 2015, Austin, Texas, USA. (Co-located with FMCAD 2015.)
ACL2 Workshop 2014: July 12-13, 2014, Vienna, Austria, as an ITP-affiliated workshop of FLoC (part of the Vienna Summer of Logic).

Jared Davis has graciously supplied a listing of bibtex entries for the 2000 through 2004 ACL2 workshops..

ACL2 input files (certifiable books) from the preceding workshops are available from the links above. WARNING: The above links point to the original versions of those books. In order to obtain up-to-date versions of those books that will certify in the latest version of ACL2, you should download workshops.tar.gz to the acl2-sources/books/ subdirectory of your ACL2 distribution, and then gunzip and extract it. On a Unix/Linux system you can then certify all the books by standing in the acl2-sources/ directory and issuing the command make regression.

ACL2 Seminar at UT

An ACL2 seminar meets regularly at the University of Texas. A list of past talks, generally accompanied by abstracts and sometimes slides, may be found on the UT ACL2 seminar page.
