The 2025 ACL2 Workshop will be held in Austin, Texas, USA, May 12-13, 2025, in a hybrid format: presenters can be in-person or remote, and both audiences will be able to watch all presentations. We invite users of ACL2, users of other theorem provers, and persons interested in the applications of theorem proving technology to attend.
Abstract submission: January 8
Paper submission: January 15
Author Notification: March 9
Camera-ready (author): April 3
Workshop: May 12-13 (reception May 11)
The ACL2 Workshop series is the major technical forum for users of the ACL2 theorem proving system to present research related to the ACL2 theorem prover and its applications. ACL2 is an industrial-strength automated reasoning system, the latest in the Boyer-Moore family of theorem provers. The 2005 ACM Software System Award was awarded to Boyer, Kaufmann, and Moore for their work on ACL2 and the other theorem provers in the Boyer-Moore family.
ACL2-2025 will be held in Austin, Texas, USA and also online, May 12-13, 2025. The workshop will take place in person on the University of Texas at Austin campus. In addition to in-person participation, the workshop will support online participation for all talks and presentations. The workshop will be the 19th in the series of ACL2 workshops, which occur approximately every 18 months. It will feature technical papers as well as rump sessions that discuss ongoing research.
Check back later for invited keynote talks.We invite submissions of papers on any topic related to ACL2 and its applications, and we strongly encourage submissions related to other theorem provers or formal methods that are of interest to the ACL2 community. Suggested topics include but are not limited to new results in the following areas.
Submissions must be made electronically in PDF format. Submissions should be prepared in the EPTCS templates, available from http://style.eptcs.org, and submitted via EasyChair at:
https://easychair.org/conferences/?conf=acl22025
The ACL2 Workshop accepts both regular papers (up to sixteen pages excluding references) and extended abstracts (up to three pages excluding references). Both categories of papers will be fully refereed and need short abstracts submitted by the "Abstract submission" deadline. Accepted submissions in both categories will be included in the final workshop proceedings, although speaking slots will be shorter for extended abstracts. At least one author of each accepted submission must register for the workshop and give a presentation summarizing the paper's results. The presentation of the paper by the author may be done in-person or online.
Extended abstracts should contain at least one or two references so someone can pursue the abstract topic. Like regular papers, extended abstracts must describe work that has already been done -- it is not for ideas for future work. To discuss future work, we will have a rump session, and we will later appeal for those topics.
One of the main advantages of the ACL2 Workshop is that attendees are already knowledgeable about ACL2, its syntax, its basic commands, and the art of writing models in it. So authors may assume that readers have this familiarity.
Many papers presented at the workshop will describe interactions
with the theorem prover. Authors of such papers are required to
provide ACL2 script files
(typically, ACL2
books) along with instructions for their use with
ACL2, unless they provide a small text file explaining why
supporting materials are not appropriate (e.g., for a theory paper;
or, you can explain where to find supporting materials that are
already in the commmunity books). Such supporting materials should
have proper licenses and copyrights (feel free to email the workshop
chairs if you have questions about that). The books should be
certifiable either with custom instructions that are clearly provided,
or by running the following shell command in the directory of your
contributed books, where ACL2_DIR denotes your ACL2
sources directory and ACL2 denotes a recent ACL2
executable.
ACL2_DIR/books/build/cert.pl --acl2 ACL2 *.lisp
Send the supporting materials or (as discussed above) a small
explanatory text file to either Ruben Gamboa
(ruben@gamboas.org)
or Pete Manolios
(pete@ccs.neu.edu).
For accepted papers, we will require authors to make these books available by adding them to the ACL2 Community Books. (Matt Kaufmann may assist in that process, if asked.)
The workshop will also feature rump sessions, in which participants can describe ongoing research related to ACL2. Proposals for rump session presentations, including a title and short abstract, should be sent to the chairs. These proposals may be accepted until the workshop, but preference will be given to early submissions and subject to available time.
Feel free to email the Organizing Chairs if you have questions.
The workshop will take place on the campus of the University of Texas in the Gates Dell Complex (GDC), North Wing, Room 6.302 (Faculty Lounge), which is located south of 24th Street on Speedway. Visitor parking is available in the parking garages, of which the San Jacinto Garage is closest to GDC.
In addition, the workshop will be held online. Details of the online participation will be forthcoming.
Here are some possibilities. Note that no block of rooms is being reserved.
There will be one or more Best Student Paper awards. Check back later for details.
We are grateful to our sponsors (listed below)!
Thanks also to Warren Hunt for, once again, serving as faculty sponsor for holding the ACL2 Workshop at UT Austin.
