The journal The Art of Discrete and Applied Mathematics (ADAM) has kindly agreed to publish a special issue devoted to SIGMAP. We encourage all conference participants to submit papers for this special issue. Papers submitted for this special issue should be on topics presented or discussed at the workshop, or closely related to them. ADAM is a modern, dynamic, platinum open access, electronic journal that publishes high-quality articles in contemporary discrete and applied mathematics (including pure and applied graph theory and combinatorics), with no costs to authors or readers. To be considered for inclusion in this special issue, papers should be submitted by December 31, 2022, via the ADAM website https://adam-journal.eu. A template and style file for submissions can be downloaded from that website, or obtained from one of the guest editors on request. The ideal length of papers is 5 to 15 pages, but longer or shorter papers will certainly be considered. Papers that are accepted will appear on-line soon after acceptance, and papers that are not processed in time for the special issue may still be accepted and published in a subsequent regular issue of ADAM.
