Submission Information

COVID-19 update: The conference and affiliated workshops will be online-only, hosted by the University of Glasgow, UK.

Important dates

Submission deadline: Friday 12 February 2021, 23:59 AoE
Notification: Wednesday 28 April 2021
Camera-ready deadline: Friday 7 May 2021

Deadlines are firm; late submissions will not be considered.

Submissions and Proceedings

ICALP proceedings are published in the Leibniz International Proceedings in Informatics (LIPIcs) series. This is a series of high-quality conference proceedings across all fields in informatics established in cooperation with Schloss Dagstuhl – Leibniz Center for Informatics. LIPIcs volumes are published according to the principle of Open Access, i.e., they are available online and free of charge.

Submission guidelines

Authors are invited to submit an extended abstract of no more than 12 pages, excluding references presenting original research on the theory of computer science. All submissions must be formatted in the LIPIcs style and submitted via Easychair to the appropriate track of the conference:

The use of pdflatex and the LIPIcs style are mandatory: papers that deviate significantly from the required format may be rejected without consideration of merit.

No prior publication and no simultaneous submission to other publication outlets (either a conference or a journal) is allowed.

Technical details necessary for a proper scientific evaluation of a submission must be included in the 12-page submission or in a clearly labelled appendix, to be consulted at the discretion of program committee members. Authors are strongly encouraged to also make full versions of their submissions freely accessible in an on-line repository such as ArXiv, HAL, ECCC.

Best Paper Awards

As in previous editions of ICALP, there will be best paper and best student paper awards for each track of the conference. In order to be eligible for a best student paper award, a paper should be authored only by students and should be marked as such upon submission.
