13th International Symposium on Parameterized and Exact Computation

The 13th International Symposium on Parameterized and Exact Computation (IPEC 2018) covers research in all aspects of parameterized and exact algorithms and complexity.

IPEC 2018 will be held on 22–24 August 2018 in Helsinki, Finland. IPEC 2018 will be part of ALGO 2018, which also hosts ALGOCLOUD, ALGOSENSORS, ATMOS, ESA, WABI, and WAOA.

Call for papers

Papers presenting original research in the area are sought, including but not limited to:

In particular, theoretically grounded studies on parameterized and exact computations and kernelization for real-world applications and algorithmic engineering are especially encouraged.


Accepted papers will be published in the symposium proceedings in the Leibniz International Proceedings in Informatics (LIPIcs) series, based at Schloss Dagstuhl. Authors of accepted papers are expected to present their work at the symposium, and to incorporate the comments from the program committee. A journal special issue is planned for selected papers presented at IPEC 2018.

Important dates


The program committee may award a Best Paper Award and a Best Student Paper Award, both of which may be exceptionally split between two or more papers. A student is someone who has not received a PhD degree before the full paper submission deadline. A paper accepted to the conference is eligible for the Best Student Paper Award if either all its authors are students, or besides student co-author(s) there is one non-student co-author that confirms, at the moment of submission, that a clear majority of conceptual work on the paper was done by the student co-author(s). In the latter case, it is moreover expected that a student gives a presentation at the conference. Papers co-authored by members of the programme committee are eligible neither for the Best Paper Award nor for the Best Student Paper Award.

Special events

An invited talk will be given by the 2018 EATCS-IPEC Nerode Prize winner. In addition, Radu Curticapean will give an invited tutorial on counting problems in parameterized complexity and there will be a session presenting the results of the 3rd Parameterized Algorithms and Computational Experiments Challenge (PACE 2018).

Submission guidelines

Authors are invited to submit an extended abstract of up to 12 pages (excluding references) in LIPIcs style, in English, describing original unpublished research. Results previously published in another conference proceedings or journal (or scheduled for publication prior to IPEC) will not be considered. Simultaneous submission of the results to another conference with published proceedings is not allowed. However, the authors are encouraged to make full versions of their submissions freely accessible in an on-line repository such as ArXiv or ECCC.

The extended abstract should contain a summary of the main results, their motivation and importance, and evidence of their correctness. All claims made in the extended abstract must be fully justified in a clearly marked appendix that will be read at the discretion of the program committee. The authors may choose to either present in the appendix only the material excluded from the extended abstract or to attach a full version of the paper as the appendix. In either case, the authors should take a particular notice that the extended abstract should present their work in a comprehensible and self-contained way and the quality of the presentation in the extended abstract will be taken into account by the programme committee.

Authors must submit their papers electronically via easychair. The use of the LIPIcs style file, which will be provided at a later date, is mandatory; no changes to font size, page margins, etc., are permitted. Program committee members (except the co-chairs) are allowed to submit papers.
