26TH INTERNATIONAL WORKSHOP ON CELLULAR AUTOMATA AND DISCRETE COMPLEX SYSTEMS (AUTOMATA 2020)
  Call for Papers
  Stockholm, Sweden,
  August 10-12, 2020
  https://automata2020.weebly.com/
* AIMS
  AUTOMATA 2020 is innovating on various fronts given the challenge of
  climate change we want to reduce the conference Carbon footprint through a
  virtual attendance option, and also by addressing the underrepresentation
  of young and minority groups in the field. The workshop aims to:
   - Establish and maintain a permanent, international, multidisciplinary
   forum for the collaboration of researchers in the field of Cellular
   Automata (CA) and Discrete Complex Systems (DCS).
   - Provide a platform for presenting and discussing new ideas and resultS
   - Support the development of theory and applications of CA and DCS (e.g.
   parallel computing, physics, biology, social sciences, and others) as long
   as fundamental aspects and their relations are concerned.
   - Identify and study within an inter- and multidisciplinary context, the
   important fundamental aspects, concepts, notions, and problems concerning
   CA and DCS.
  As it is its tradition, *AUTOMATA 2020* will focus on the theory and
  application of cellular automata and discrete dynamical systems in
  connection to complexity theory and algorithmic information. There will be
  special sessions on *Automata in Deep Learning* and *Algorithmic
  Information Dynamics* with a particular interest in aspects of
  computability in causation and reprogrammability.
* SUBMISSION GUIDELINES
  Submissions presenting original and unpublished research on all
  fundamental aspects of cellular automata and related discrete complex
  systems are being sought. Topics of interest include (but are not limited to):
   - algorithmic information dynamics
   - dynamic, topological, ergodic and algebraic aspects
   - algorithmic and complexity issues
   - emergent properties
   - formal languages
   - symbolic dynamics
   - tilings
   - models of parallelism and distributed systems
   - synchronous versus asynchronous models
   - phenomenological descriptions and scientific modelling
   - applications of CAs and DCSs
  There are two categories of submission - full papers and exploratory
  papers. Full papers are meant to report more complete and denser
  research, while the later submission deadline for exploratory papers
  allows short reports of recent discoveries, work-in-progress and/or
  partial results. Submissions in the full paper category are refereed
  and selected by the program committee. Papers in the exploratory
  category go through a less rigorous evaluation process. All accepted
  papers must be presented (in person or virtually) at the conference.
  Authors are invited to submit papers of no more than 12 pages
  (for full papers) or 8 pages (for exploratory papers) by following the
   following link: https://easychair.org/conferences/?conf=automata2020
  Submissions should contain original research that has not previously
  been published.

NATURAL LOGIC MEETS MACHINE LEARNING (NALOMA'2020)
  Call for Papers
  July 11-17, 2020
  Brandeis University, Waltham MA USA
  Workshop at NASSLLI 2020
  https://typo.uni-konstanz.de/naloma20/
* AIMS
  NAtural LOgic Meets MAchine Learning (NALOMA) is the first workshop of its
  kind, aiming to bridge the gap between Machine Learning and Natural Logic.
  It will take place from July 11-July 17, 2020, during the 9th North
  American Summer School for Logic, Language, and Information (NASSLLI) at
  Brandeis University in Waltham, Massachusetts.
  Recent models of Natural Language Inference (NLI) have made considerable
  progress in the last couple of years and have achieved performance at
  nearly human-level. Even though this last statement might still be an
  exaggeration, it is indeed true that NLI models are capable of doing more
  things than we thought they would some years ago. On the other hand,
  research on symbolic methods for NLI has not been fully abandoned. One such
  area that is still flourishing is research on Natural Logic. There is
  actually renewed interest in monotonicity inference, and connections with
  theorem provers and tableau systems from standard areas of logic.
  Within this context, the aim of this workshop is to bring together
  researchers working in both Natural Logic and Machine Learning approaches
  to NLI, initiating a discussion with the two sets of researchers that have
  been largely unconnected up to now.
* TOPICS
  We invite submissions on topics included but not limited to:
  - reasoning systems that integrate logic-based methods with neural networks;
  - creation, evaluation, and criticism of NLI datasets;
  - training data augmentation using logic;
  - explainable models of NLI;
  - opening the "black box" of machine learning in NLI;
  - probabilistic semantics in connection with NLI;
  - downstream applications of NLI;
  - comparison and contrast between human-level and machine-level work in NLI;
  - linguistics semantics and contemporary NLI.
  - dialogue systems, QA and information retrieval systems that use (natural) logic
  and machine learning.
* SUBMISSIONS
  We accept two types of submission:
  -  Archival (long or short) papers should report on complete, original and
  unpublished research. Accepted papers will be published in the workshop
  proceedings and will appear in the ACL anthology.
   - Extended abstracts may report on work in progress or work that was
  recently published/accepted at a different venue. Extended abstracts will
  not be included in the workshop proceedings. Thus, the unpublished work
  will retain the status and can be submitted to another venue. Extended
  abstracts will be linked at the workshop webpage.
  Authors must submit non-anonymized extended abstracts or papers before
  April 15. Both extended abstracts and papers must be formatted according to
  the ACL style. The extended abstracts should not contain an abstract
  section and may consist of up to 2 pages of content, plus unlimited
  references. Short and long papers may consist of up to 4 and 8 pages of
  content, respectively, plus unlimited references. Camera-ready versions of
  papers will be given one additional page of content so that reviewers'
  comments can be taken into account.
  Both extended abstracts and follow-up papers should be submitted via
  EasyChair at https://easychair.org/conferences/?conf=3Dnlmml20
* INVITED SPEAKERS
  Lauri Karttunen, Stanford University
  Ellie Pavlick, Brown University
  Mark Steedman, University of Edinburgh
* IMPORTANT DATES

  Call for Talk Proposals
  Associated with the 32nd International Conference on Computer-Aided Verification (CAV 2020)
  Los Angeles, CA, United States, July 19, 2020
  https://easychair.org/cfp/PERR-2020
* COVID
  Given the rapidly evolving situation regarding COVID-19, the date of
  the workshop may change. Please follow the CAV webpage for details.
* WORKSHOP
  PERR is an annual international workshop dedicated to the formal
  verification of program equivalence and related relational problems.
  It is the 4th in a series of meetings that bring together researchers
  from different areas interested in equivalence and related questions.
  Last year's PERR was held as a satellite workshop of ETAPS.
  PERR 2020 is affiliated with CAV.
* AIMS
  Program equivalence is arguably one of the most interesting and at
  the same time important problems in formal verification. It is a
  cross-cutting topic that has attracted the interest of several research
  communities: denotational semantics, deductive software verification,
  bounded model checking, specification inference, software evolution
  and regression testing, etc. The goal of the workshop is to stimulate
  an exchange of ideas to forge a community working on Program
  Equivalence and Relational Reasoning (PERR). The workshop
  welcomes contributions on the topics mentioned below but is also
  open to new questions regarding program equivalence. This includes
  related research areas of relational reasoning like program refinement
  or the verification of hyperproperties, in particular of secure information
  flow.
* AREAS
  regression verification, program equivalence, equivalence of
  higher-order programs, product programs, relational calculi,
  verification of hyperproperties, program refinement, refinement
  calculus, specification of differences between programs, inferring
  semantic differences between programs, transformation validation,
  correct compiler transformations, automata bisimulation, code
  equivalence checking in teaching and marking
* SUBMISSION
  This is an informal workshop that welcomes work in progress,
  overviews of more extensive work, programmatic or position papers
  and tool presentations. The workshop will have informal online proceedings.
  Please submit a short abstract (1-2 pages) of your proposed talk via EasyChair.

INTERNATIONAL WORKSHOP ON QUANTIFIED BOOLEAN FORMULAS AND BEYOND (QBF 2020)
  Call for Papers
  Alghero, Italy, July 5, 2020
  Affiliated to and co-located with SAT 2020
  https://www.ac.tuwien.ac.at/qbf2020/
* COVID
  The workshop/conference organization is monitoring the COVID-19
  situation, and we hope to do our best to support the form of dialogue
  that this workshop aims to promote.  For now, we would encourage those
  interested in submitting to the workshop to proceed in doing so; given
  the situation, we plan to give authors of accepted works a chance to
  confirm their willingness to participate prior to finalizing this.
* TOPIC
  Quantified Boolean formulas (QBF) are an extension of propositional
  logic which allows for explicit quantification over propositional
  variables. The decision problem of QBF is PSPACE-complete, compared to
  the NP-completeness of the decision problem of propositional logic (SAT).
  The goal of the International Workshop on Quantified Boolean Formulas
  (QBF Workshop) is to bring together researchers working on theoretical
  and practical aspects of QBF solving. In addition to that, it
  addresses (potential) users of QBF in order to reflect on the
  state-of-the-art and to consolidate on immediate and long-term
  research challenges. The workshop also welcomes work on reasoning
  with quantifiers in related problems, such as dependency QBF (DQBF),
  quantified constraint satisfaction problems (QCSP), and satisfiability
  modulo theories (SMT) with quantifiers.
* IMPORTANT DATES
  April 24: Submission via Easychair
  May 12: Notification of acceptance
  May 28: Final versions of accepted papers due
  July 5: Workshop
 * SUBMISSIONS
  Submissions of extended abstracts are invited and will be managed via Easychair.
  In particular, we invite the submission of extended abstracts on work
  that has been published already, novel unpublished work, or work in
  progress. The following forms of submissions are solicited:
  - Proposals for short tutorial presentations on topics related to the
  workshop. Tutorial proposals will be reviewed by the PC. The number
  of accepted tutorials depends on the overall number of accepted
  papers and talks, with the aim to set up a balanced workshop
  program.
  - Talk abstracts reporting on already published work. Such an abstract
  should include an outline of the planned talk, and pointers to
  relevant bibliography.
  - Talk proposals presenting work that is unpublished or in progress.
  - Submissions which describe novel applications of QBF or related
  formalisms in various domains are particularly welcome.
  Additionally, this call comprises known applications which have been
  shown to be hard for QBF solvers in the past as well as new
  applications for which present QBF solvers might lack certain
  features still to be identified.
  Each submission should have an overall length of 1-4 pages in LNCS
  format. Authors may decide to include an appendix with additional
  material. Appendices will be considered at the reviewers' discretion.
  The accepted extended abstracts will be published on the workshop
  webpage. The workshop does not have formal proceedings.
  Authors of accepted contributions are expected to give a talk at the
  workshop.

4TH ANNUAL WORKSHOP ON STRING DIAGRAMS IN COMPUTATION, LOGIC, AND PHYSICS (STRINGS 2020)
  Call for Papers
  Satellite workshop of STAF 2020
  Bergen, Norway, 23 June 2020
  https://compose.ioc.ee/strings2020/
* SCOPE
  String diagrams are a powerful tool for reasoning about processes and
  composition. Originally developed as a convenient notation for the
  arrows of monoidal and higher categories, they are increasingly used in
  the formal study of digital circuits, control theory, concurrency,
  programming languages, quantum and classical computation, natural language,
  logic and more. String diagrams combine the advantages of formal syntax
  with intuitive aspects: the graphical nature of terms means that they
  often reflect the topology of systems under consideration. Moreover,
  diagrammatic reasoning transforms formal arguments into dynamic, moving
  images, thus building domain specific intuitions, valuable both for
  practitioners and pedagogy.
* AIMS
  This workshop aims to bring together researchers from diverse
  backgrounds and specialities to collaborate and share their insights,
  tools, and techniques. STRINGS 2020 is a satellite event of STAF 2020,
  colocated with a number of related events, including Diagrammatic and
  Algebraic Methods for Business (DAMB) and the International Conference
  on Graph Transformation (ICGT).
* HISTORY
  This is the fourth edition of the workshop. The first was held
  in Oxford in 2017, the second as a Shonan workshop in 2018, the third
  in Birmingham in 2019.
* INVITED SPEAKER
  Fabio Zanasi, UCL

THE SYMPOSIUM ON PRINCIPLES OF DATABASE SYSTEMS  (PODS)
  Expected to take place in Xi'an, China, in June 2021
  (subject to possible change due to the Coronavirus)
  https://databasetheory.org/node/110
* AIMS
  The Principles of Database Systems (PODS) symposium series, held in
  conjunction with the SIGMOD conference series, provides a premier annual
  forum for the communication of new advances in the theoretical foundations
  of data management, traditional or non-traditional
  (see https://databasetheory.org/PODS).
* TOPICS
  For the 40th edition, PODS continues to aim to broaden its scope, and
  calls for research papers providing original, substantial contributions along
  one or more of the following tracks:
   - deep theoretical exploration of topical areas central to data management
  - new formal frameworks that aim at providing a basis for deeper theoretical
  investigation of important emerging issues in data management
  - validation of theoretical approaches from the lens of practical applicability
  in data management. Papers in this track should provide an experimental
  evaluation that gives new insight in established   theories. Besides, they
  should provide a clear message to the database theory community as to
  which aspects need further (theoretical) investigation, based on the
  experimental findings.
* SUBMISSION FORMAT
  Submitted papers should be at most twelve pages, including bibliography.
  Additional details may be included in an appendix that should be incorporated
  at the submission time (online appendices are not allowed). However,
  such appendices will be read at the discretion of the program committee.
  Papers that are longer than twelve pages (including bibliography but
  excluding the appendix) or do not cohere with the ACM proceedings style
  risk rejection without consideration of their merits. PODS 2021 specifically
  encourages the submission of shorter papers as well as papers that make
  use of the full page allowance. The submission process will be through the
  Web at https://easychair.org/conferences/?conf=pods2021. Note that PODS
  does not use double-blind reviewing, and therefore PODS submissions
  should have the names and affiliations of authors listed on the paper. The
  results of a submitted paper must be unpublished and not submitted elsewhere,
  including the formal proceedings of other symposia or workshops. Authors of
  an accepted paper will be expected to sign copyright release forms, and one
  author is expected to present it at the conference. PODS supports the
  open-access of published research. It is therefore expected that authors of
  accepted papers will make the final version of their papers also freely accessible
  on arXiv by the camera-ready deadline.
 * FIRST SUBMISSION CYCLE
  June 26, 2020: Abstract submission
  July 03, 2020: Paper submission
  September 18, 2020: First notification
  October 16, 2020: Revised submission

  An award will be given to the best submission, as judged by
  the program committee.
  - Best Student Paper Award:
  There will also be an award for the best submission, as judged by
  the program committee, written by a student or exclusively by students.
  An author is considered as a student if, at the time of submission,
  the author is enrolled in a program at a university or institution leading
  to a doctoral/master?s/bachelor?s degree.
  The program committee reserves the right to give both awards to the same paper,
   not to give an award, or to split an award among several papers. Papers authored
   or co-authored by program committee members are not eligible for an award.

SYMPOSIUM ON PRINCIPLES OF PROGRAMMING LANGUAGES (POPL 2021)
  Call for Papers
  Sun 17 - Fri 22 Jan 2021: Conference
  https://popl21.sigplan.org/
* COVID
  POPL 2021 will take place during the announced dates, as a physical or
  virtual meeting. We will be monitoring the Covid-19 situation and will
  announce a decision on the nature of the meeting.  The paper
  submission deadline is firm and not subject to change.
* CHAIRS
  General chair: Andreas Podelski
  Program chair: Azadeh Farzan
* DATES
  Thu 09 Jul 2020: Submission deadline
  Sun 17 - Fri 22 Jan 2021: Conference
* SCOPE
  The annual Symposium on Principles of Programming Languages is a forum
  for the discussion of all aspects of programming languages and
  programming systems. Both theoretical and experimental papers are
  welcome, on topics ranging from formal frameworks to experience
  reports. We seek submissions that make principled, enduring
  contributions to the theory, design, understanding, implementation or
  application of programming languages. The symposium is sponsored by
  ACM SIGPLAN, in cooperation with ACM SIGACT and ACM SIGLOG.
* EVALUATION
  For details about evaluation, PACMPL and copyright, see the full POPL CfP.
  The following two points are easy to overlook:
  - Conflicts: Each author of a submission has to log into the
    submission system and properly declare all potential conflicts of
    interest in the author profile form. A conflict caught late in the
    reviewing process leads to a voided review which may be infeasible
    to replace.
  - Anonymity: POPL 2021 will employ a lightweight double-blind
    reviewing process. Make sure that your submitted paper is fully
    anonymized.
  Prior to the paper submission deadline, the authors will upload their
  full anonymized paper. Each paper should have no more than 25 pages of
  text, excluding bibliography, using the new ACM Proceedings format.
* ARTIFACTS
  Authors of accepted papers will be invited to formally submit
  supporting materials to the Artifact Evaluation process. Artifact
  Evaluation is run by a separate committee whose task is to assess how
  the artifacts support the work described in the papers. This
  submission is voluntary and will not influence the final decision
  regarding the papers. Papers that go through the Artifact Evaluation
  process successfully will receive a seal of approval printed on the
  papers themselves. Authors of accepted papers are encouraged to make
  these materials publicly available upon publication of the
  proceedings, by including them as "source materials" in the ACM
  Digital Library.
* PUBLICATION AND PRESENTATION
  - Papers may not be presented at the conference if they have not been
  published by ACM under one of the allowed copyright options.  All
  papers will be archived by the ACM Digital Library. Authors will have
  the option of including supplementary material with their paper.
  - The official publication date is the date the proceedings are made
  available in the ACM Digital Library. This date may be up to two weeks
  prior to the first day of the conference. The official publication
  date affects the deadline for any patent filings related to published
  work.
  - Authors of accepted papers are required to give a short talk (roughly
  25 minutes long) at the conference, according to the conference
  schedule.
* DISTINGUISHED PAPER AWARDS
  At most 10% of the accepted papers of POPL 2021 will be designated as
  Distinguished Papers. This award highlights papers that the POPL
  program committee thinks should be read by a broad audience due to
  their relevance, originality, significance and clarity. The selection
  of the distinguished papers will be made based on the final version of
  the paper and through a second review process.
