We invite submissions to the special issue of Discrete Applied Mathematics dedicated to the Ninth Workshop on Graph Classes, Optimization, and Width Parameters, GROW 2019.

Submission is also open to researchers who did not attend GROW 2019 and the papers may, but need not, be related to a presentation at the workshop.

Contributions arising from papers already published in conference proceedings should be substantially extended and should cite the conference presentation where appropriate. All articles will be thoroughly refereed according to the high standards of Discrete Applied Mathematics.

The full papers must be submitted through the Elsevier Editorial System (https://www.editorialmanager.com/DAM/default.aspx); make sure to select the article type “Special Issue: GROW 2019”, so that your paper will be assigned to the guest editors.

DEADLINE: Submission will open in the next days, and the deadline for submission is July 1, 2020. Accepted papers will be published online individually before print publication.

If you are considering submitting a paper to the special issue, please let us know via a brief email to grow2019@ac.tuwien.ac.at by the end of the year.

Guest Editors: Robert Ganian, Jan Kratochvil, Stefan Szeider
