The ACM SIGPLAN Workshop on Partial Evaluation and Program Manipulation (PEPM), which has a history going back to 1991 and has co-located with POPL every year since 2006, originates in the discoveries of practically useful automated techniques for evaluating programs with only partial input. Over the years, the scope of PEPM has expanded to include a variety of research areas centred around the theme of semantics-based program manipulation — the systematic exploitation of treating programs not only as subject to black-box execution, but also as data structures that can be generated, analysed, and transformed while establishing or maintaining important semantic properties.

Call for Papers


In addition to the traditional PEPM topics (see below), PEPM 2018 welcomes submissions in new domains, in particular:

  • Semantics based and machine-learning based program synthesis and program optimisation.

  • Modelling, analysis, and transformation techniques for distributed and concurrent protocols and programs, such as session types, linear types, and contract specifications.

More generally, topics of interest for PEPM 2018 include, but are not limited to:

  • Program and model manipulation techniques such as: supercompilation, partial evaluation, fusion, on-the-fly program adaptation, active libraries, program inversion, slicing, symbolic execution, refactoring, decompilation, and obfuscation.

  • Techniques that treat programs/models as data objects including metaprogramming, generative programming, embedded domain-specific languages, program synthesis by sketching and inductive programming, staged computation, and model-driven program generation and transformation.

  • Program analysis techniques that are used to drive program/model manipulation such as: abstract interpretation, termination checking, binding-time analysis, constraint solving, type systems, automated testing and test case generation.

  • Application of the above techniques including case studies of program manipulation in real-world (industrial, open-source) projects and software development processes, descriptions of robust tools capable of effectively handling realistic applications, benchmarking. Examples of application domains include legacy program understanding and transformation, DSL implementations, visual languages and end-user programming, scientific computing, middleware frameworks and infrastructure needed for distributed and web-based applications, embedded and resource-limited computation, and security.

This list of categories is not exhaustive, and we encourage submissions describing new theories and applications related to semantics-based program manipulation in general. If you have a question as to whether a potential submission is within the scope of the workshop, please contact the programme co-chairs, Fritz Henglein and Josh Ko.

Submission categories and guidelines

Two kinds of submissions will be accepted: Regular Research Papers and Short Papers.

  • Regular Research Papers should describe new results, and will be judged on originality, correctness, significance, and clarity. Regular research papers must not exceed 12 pages (excluding bibliography).

  • Short Papers may include tool demonstrations and presentations of exciting if not fully polished research, and of interesting academic, industrial, and open-source applications that are new or unfamiliar; they will be evaluated primarily on the basis of their ideas rather than finished execution. Short papers must not exceed 6 pages (excluding bibliography), and should include the words “short paper” somewhere in their titles.

Both kinds of submissions should be typeset using the two-column sigplan sub-format of the new acmart format available at:


and submitted electronically via HotCRP:


PEPM 2018 will employ lightweight double-blind reviewing according to the rules of POPL 2018. Quoting from POPL 2018’s call for papers:

submitted papers must adhere to two rules:

  1. author names and institutions must be omitted, and

  2. references to authors’ own related work should be in the third person (e.g., not “We build on our previous work …” but rather “We build on the work of …”).

The purpose of this process is to help the PC and external reviewers come to an initial judgment about the paper without bias, not to make it impossible for them to discover the authors if they were to try. Nothing should be done in the name of anonymity that weakens the submission or makes the job of reviewing the paper more difficult. In particular, important background references should not be omitted or anonymized. In addition, authors should feel free to disseminate their ideas or draft versions of their paper as they normally would. For instance, authors may post drafts of their papers on the web or give talks on their research ideas.

See POPL 2018’s Submission and Reviewing FAQ page for more information.

Submissions are welcome from PC members (except the two co-chairs) provided that there are non-PC co-authors.

Accepted papers will appear in formal proceedings published by ACM, and be included in the ACM Digital Library. Authors of short papers, however, can ask for their papers to be left out of the formal proceedings.

At least one author of each accepted contribution must attend the workshop and present the work. In the case of tool demonstration papers, a live demonstration of the described tool is expected. Suggested topics, evaluation criteria, and writing guidelines for both research tool demonstration papers will be made available on the PEPM 2018 web site.

Student participants with accepted papers can apply for a SIGPLAN PAC grant to help cover travel expenses and other support. PAC also offers other support, such as for child-care expenses during the meeting or for travel costs for companions of SIGPLAN members with physical disabilities, as well as for travel from locations outside of North America and Europe. For details on the PAC programme, see its web page.

Important dates

  • Paper submission deadline: Friday 6th October 2017 (AoE) (firm)
  • Author notification: Saturday 4th November 2017
  • Workshop: Monday 8th – Tuesday 9th January 2018

The proceedings will be published 2 weeks pre-conference.

AUTHORS TAKE NOTE: 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 your conference. The official publication date affects the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)

Best paper award

PEPM 2018 continues the tradition of a Best Paper award. The winner will be announced at the workshop.
