FINAL CALL FOR PAPERS

Special Issue on Parameterized and Approximation Algorithms in Graph Drawing
of
Journal of Graph Algorithms and Applications (JGAA)



Dear Colleagues,

It is a great pleasure to invite you to submit a paper to the Special
Issue of Journal of Graph Algorithms and Applications (JGAA) on
"Parameterized and Approximation Algorithms in Graph Drawing".

In the course of a few decades, the fields of parameterized complexity
and approximation algorithms have emerged as distinguished research
areas providing an impressive collection of broadly usable
methodologies and remarkable theoretical and practical contributions.
These branches of complexity theory provide a framework of powerful
techniques that allow us to tackle hard (often NP-hard) problems, by
either considering restricted graph classes or by seeking solutions
"close" to the optimal ones. Moreover, in recent years, the research
efforts in these two fields have converged into the study of the
unified notion of parameterized approximation algorithms.

Submission Deadline: *March 25, 2022 (extended).*


Topics
======

The emphasis of this special issue is on original results in the areas
of fixed-parameter tractable and approximation algorithms in graph
drawing and network visualization. This includes, but is not limited
to, theoretical and combinatorial aspects that arise at the interface
of graph drawing with computational and discrete geometry,
combinatorial optimization, visual computing, VLSI and computer-aided
design, computer graphics, and information visualization. The range of
topics includes:

- fixed-parameter tractable and approximation algorithms
- (parameterized) inapproximability
- W[k]-hardness
- parameterized approximations
- (lossy) kernelization
- fine-grained complexity of approximations
- subexponential-time approximations

Other topics that are not listed but that might be of interest for the
study of parameterized and approximation algorithms in graph drawing
will also be evaluated. To bridge the gap between theory and practice,
we welcome contributions dealing with techniques and data structures
to obtain efficient parameterized and approximation algorithms to
tackle graph-visualization problems as well as implementations,
experimental evaluations, and algorithm engineering issues of
approximation, parameterized, and kernelization algorithms that emerge
in practice.


Paper Submission
================

We invite authors to submit papers describing original research of
theoretical or practical significance concerned with parameterized and
approximation algorithms in graph drawing and network visualization
until March 25, 2022. We aim for a fast reviewing process in order to
have this special issue available at the end of 2022. Papers should be
submitted to the editors of the special issue in PDF format. All
communications between the editors, authors, and reviewers will be
done by email unless otherwise requested by the author or reviewer.
All submissions must be formatted using the LaTeX style file of
Journal of Graph Algorithms and Applications
(http://jgaa.info/authors.jsp). The default margins and fonts must not
be modified. The submission should contain a scholarly exposition of
ideas, techniques, and results, including motivation and a clear
comparison with related work. The claims of the paper should be fully
substantiated, including full proofs or appropriate experimental data.
Papers of good quality that do not fit within the scope of this
special issue might be handled as regular JGAA submissions.
