[Second Call for Papers, sent June 11, 2018] ACL2 2018 15th International Workshop on the ACL2 Theorem Prover and Its Applications November 5-6, 2018, Austin, Texas, USA http://www.cs.utexas.edu/users/moore/acl2/workshop-2018/index.html The 2018 ACL2 Workshop will be held in Austin, Texas, USA, and it is co-located with FMCAD (http://www.fmcad.org/FMCAD18). We invite users of ACL2, users of other theorem provers, and persons interested in the applications of theorem proving technology to attend. IMPORTANT DATES: Abstract submission: June 30, 2018 Paper submission: July 7, 2018 Author notification: August 25, 2018 Camera ready: September 25, 2018 Workshop: November 5-6, 2018 AIMS AND SCOPE: 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 in ACL2 and the other theorem provers in the Boyer-Moore family. ACL2-2018 is a two-day workshop to be held in Austin, Texas, USA, on November 5-6, 2018, immediately after the weekend following FMCAD (http://www.fmcad.org/FMCAD18), on the University of Texas campus. It is the 15th in the series of ACL2 workshops, which occur approximately every 18 months. The workshop will feature technical papers as well as rump sessions that discuss ongoing research. There will be three invited keynote talks, given by: Sandip Ray, University of Florida at Gainesville Alastair Reid, ARM Sol Swords, Centaur Technology 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. * Software or hardware verification with ACL2 * Formalizations of mathematics in ACL2 * Libraries and tools for ACL2 * User interfaces for ACL2 * Novel uses of ACL2 * Experiences with ACL2 in the classroom * Reports of and proposals for improvements of ACL2 * Comparisons with other theorem provers * Comparisons with other programming or specification languages * Challenge problems and their solutions * Foundational issues related to ACL2 * Implementations connecting ACL2 with other systems PAPER SUBMISSIONS: 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. See the ACL2 2018 website for details. The ACL2 Workshop accepts both long papers (up to sixteen pages) and extended abstracts (up to two pages). Both categories of papers will require short abstracts to be submitted by the "Abstract submission" deadline and will be refereed by at least two members of the program committee. 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. Extended abstracts should contain at least one or two references so someone can pursue the abstract topic. Like long 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. The workshop proceedings will be published as a volume of Electronic Proceedings in Theoretical Computer Science (EPTCS). Long papers will be published as PDFs, and extended abstracts will be published as HTML snippets. Please see the EPTCS copyright page (http://copyright.eptcs.org/) for a discussion of licensing. Please also see the EPTCS LaTeX style file and formatting instructions (http://style.eptcs.org). 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). 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 to Matt Kaufmann, kaufmann@cs.utexas.edu. For accepted papers, we will require authors to make these books available by adding them to the ACL2 Community Books. (The chairs may assist in that process, if asked.) The authors can expect the reviewers to take the supporting materials into account during the refereeing process. 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, may be accepted until the workshop, but preference will be given to early submissions and subject to available time.

HISTORICAL INFORMATION: The ACL2 Workshop series has previously published with EPTCS in 2011, 2013, 2014, 2015, and 2017. In other past years: the proceedings were published with Springer LNCS 6172 in 2010, and ACM digital library in 2006 and 2009. The first ACL2 workshop in 1999 resulted in two books: - Computer-Aided Reasoning: An Approach, Kaufmann, Manolios, Moore, Kluwer, (May, 2000) - Computer-Aided Reasoning: ACL2 Case Studies, Kaufmann, Manolios, Moore (eds), Kluwer, (May, 2000) ACL2 workshops have been co-located with major conferences in formal methods in the past: European Joint Conferences on Theory and Practice of Software (ETAPS) in 2002, Computer-Aided Verification (CAV) in 2003, Federated Logic Conference (FLoC) in 2006, 2010, and 2014, and Formal Methods in Computer-Aided Design (FMCAD) in 2004, 2007, 2011, 2015, and 2018.
