Systems of Systems (SoSs) are gaining momentum due to the widespread adoption
of Internet of Things (IoT) technologies, an increasing interest for smart
cities, digital twins, and industrial cyber physical systems. The heterogeneity
and large scale of these systems require novel design techniques, architectures
and software infrastructures able to integrate independent (sub)systems to
support their seamless cooperation, even through emergent behaviors. In
addition, the continuous servicing process enabled by the recent micro-services
paradigm leads to rely on evolving approaches able to anticipate, mitigate, or
react to unplanned scenarios.

Each system of a SoS must both exist as an independent entity and become part
of wider systems when needed. This vision radically changes the notion of
“integrated” system: (a) (sub)systems offer limited interaction capabilities
and little possibility to be controlled; (b) cooperation can be ad-hoc and only
needed in specific cases or conditions; (c) in many cases there is no prior,
complete, knowledge of the (sub)systems; (d) SoS behaviors can be partially
unplanned to follow environment or requirement changes.

The goal of the GAUSS (Governing Adaptive and Unplanned Systems of Systems)
workshop is to bring together researchers and practitioners working on the
design, the development, the validation, and the continuous maintenance of
System of Systems. In this context, specific emphasis to methods and approaches
focusing on ensuring desired sets of quality attributes (e.g., reliability,
security, resilience) that SoSs must satisfy is given.

In addition, research works on distributed and adaptive system are also subject
of interest for the GAUSS Workshop. Indeed, topics on dynamic modules
integration, autonomous reaction to unplanned scenarios, or dynamic evolution
of operational and managerial assets are source of changes that often
potentially affect the overall environment (i.e. the SoS) too, consequently
they are in the scope of the workshop too.

The GAUSS workshop will accept regular papers reporting on new research, and
presentations of Journal First Papers. In addition, the organizing committee is
planning to invite the best regular papers for a special issue on a Journal
related to the topics of the Workshop (to be decided).

===== Venue ======

The 2nd Edition of the International Workshop GAUSS will be held in conjunction
with the 31st edition of the ISSRE Conference that will be held in Coimbra,
Portugal, Oct 12 - 15, 2020.
Due to the Covid outbreak, both the main conference and the workshop will be virtual.
Information regarding how to follow the events will be provided in the next future.

=================================================================
========================= Regular Papers ========================
=================================================================

Papers submitted for evaluation must be original, unpublished, and not
submitted for publication elsewhere.

Any submission of a contribution implies that, if accepted for presentation, at
least one of its proponents must register (paying the requested fee) and attend
the conference for giving the presentation.

===== Submissions =====

Authors should submit an electronic copy of the paper (written in English) in
PDF using the EasyChair submission site:
* https://easychair.org/my/conference?conf=issre2020

Submissions must adhere to the IEEE CS Format Guidelines (for more information
see at https://www.ieee.org/conferences/publishing/templates.html).
GAUSS 2020 accepts two categories of papers:
* LONG: up to 8 pages (with references)
* SHORT: up to 4 pages (with references)

Papers that exceed the number of pages for their submission category could be
rejected without review.

===== Dates =====

* Abstract submission deadline: July 24th [**not mandatory**]
* Full paper submission deadline: August 3rd, 2020
* Notification to authors: August 21st, 2020
* Camera-ready papers: August 28th, 2020

===== Publication =====

Accepted peer-reviewed papers will be included in a supplemental volume of the
ISSRE conference proceedings, and published by the IEEE Computer Society on
IEEE Xplore.

We plan to invite some selected papers to submit an extended version to a
special issue on a Journal related to the topics of the Workshop (to be
decided).

=================================================================
================== Special Track: Journal First =================
=================================================================

This year GAUSS will have a dedicated session to promote the community meeting
and research sharing, accepting already published papers on journals related to
the topics of the workshop.

Authors who had articles published on eligible journals between January 1st,
2019 and August 3rd, 2020 can propose their work to the JF Track of GAUSS. The
proposed papers must be in the scope of the workshop; furthermore, they must
not be an extension of previous Conference/Workshop papers, and they must have
not already been presented in similar JF tracks.

Journals are eligible for the JF track if they:
* are indexed on Scimago at: https://www.scimagojr.com/
* are in subjects areas and categories related to the workshop (e.g.,
Computer Science, Software, Artificial Intelligence, etc.)
* have an average evaluation of Q2 (or more) in the last 4 years (2015-2018)
in these categories

Please note that the papers in the JF Track will not be evaluated again by
reviewers: their quality is already assured by the journals where they are
published. The selection process will only refer to the relevance and the
affinity of the papers with respect to the workshop topics and the availability
of the foreseen presentation slots.

===== JF Track Submissions =====

Authors should submit an electronic record (written in English) in PDF using
the EasyChair submission site:
* https://easychair.org/my/conference?conf=issre2020

Each record submission for the JF Track must include:
* the title of the original article
* the complete list of authors
* the original abstract
* a list of keywords
* the full reference to the article as accepted by the journal (plus a link to the online version, if any)
* if available, authors can include a public version of the paper too (e.g., pre-print, arXiv link, etc.) [**not mandatory**]

===== Dates =====

* Record submission deadline: August 3rd, 2020
* Notification to authors: August 28th, 2020

===== Presentation =====

All the papers accepted to the JF Track will have a presentation slot to
promote their work during GAUSS 2020. Please note that these papers will not be
included in the proceedings: only the Title, Authors and Abstract will appear
on the websites, plus a mandatory reference to the already published paper.

Any accepted submission to the JF Track implies that at least one of its
proponents must register (paying the requested fee) and attend the conference
for giving the presentation.
