OVERVIEW
==================================================

Reconfigurable Transition Systems (RTS) are dynamic relational structures 
(graphs) that evolve along its execution, in the sense that their 
accessibility relation, their set of nodes or their labelling change when 
their edges are crossed. These structures have proven to be suitable to 
compactly represent complex reactive and reconfigurable behaviours. Namely, 
the ability of reacting or readapting under the influence of certain events 
is a very distinctive feature of many diverse situations and objects. An 
autonomous vehicle that changes its route due to a new strike occurring, the 
behaviour of a software component after a memory disposal, or a DNA mutation 
as the result of a viral infection, are different examples that witness the 
importance of modelling about changes in a determined situation. Practical 
user cases have aroused the interest of the logic community in the study of 
variants of RTS, by developing formal methods to properly reason about such 
situations.

This workshop aims to bring together the whole community of researchers 
working on different ways to model reconfigurable and reactive systems from a 
formal perspective. This includes theoretical approaches (like hybrid logics, 
reactive frames, model-update logics, and topological and algebraic 
semantics), or formalisms designed for specific purposes (like separation 
logic in software verification, dynamic epistemic logic in AI planning, and 
others). Also, our goal is to devise novel approaches and potential 
applications, and share a common perspective on the discipline.

==================================================
SUBMISSION GUIDELINES
==================================================

Authors are invited to submit, via CMT, research contributions or experience 
reports (https://cmt3.research.microsoft.com/reacts2025).

All papers should be written in English and prepared using the specific LNCS 
templates available at http://www.springer.de/comp/lncs/authors.html.

There are two categories of submissions:

 - FULL PAPERS up to 12 pages (excluding references) – to present original 
research and the analysis, interpretation and validation of the research 
findings.

 - SHORT PRESENTATIONS up to 4 pages (excluding references) – to present work 
in progress and preliminary results.

Both kinds of submissions allow system descriptions,  to present a new tool, 
a new tool component or novel extensions to an existing tool aiming at 
supporting open community approaches, or the use/customisation of an existing 
tool in the context of RTS.

Accepted full papers will be included in the workshop programme and will 
appear in the workshop LNCS proceedings.

Accepted short presentations will be included in the pre-proceeding 
(available online before the Workshop) but not published in the LNCS 
proceedings.

PUBLICATION
==================================================

Accepted full papers will be published by Springer in a volume of Lecture 
Notes in Computer Science (http://www.springer.com/lncs), which will collect 
contributions to some workshops co-located with SEFM 2025.

Condition for inclusion in proceedings is that at least one of the co-authors 
has presented the paper at the Workshop.

Similarly to the last edition of ReacTS, we plan to invite authors of 
selected contributions to submit extended versions to a special issue, e.g. 
to the Journal of Applied Logics.
