SECOND 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: *February 28, 2022.*


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
February 28, 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.
