The 12th International Symposium on Games, Automata, Logics, and Formal
Verification will be held in Padua (Italy) on September 20-22, 2021. This year,
GandALF will be organised together with the 3rd Workshop on Artificial
Intelligence and fOrmal VERification, Logic, Automata, and sYnthesis (OVERLAY
2021, https://overlay.uniud.it/workshop/2021/). The OVERLAY workshop focuses on
the relationships between Artificial Intelligence and Formal Methods, and
discusses the opportunities and challenges at the border of the two areas.
Both events will be hosted by the University of Padua, and will share some
invited speakers. We encourage participation in both events. GandALF 2021 is
planned to be a hybrid conference. We aim at organizing an in-presence event,
but there will be possibilities for virtual participation for delegates
affected by travel restrictions.

The aim of GandALF 2021 is to bring together researchers from academia and
industry which are actively working in the fields of Games, Automata, Logics,
and Formal Verification. The idea is to cover an ample spectrum of themes,
ranging from theory to applications, and stimulate cross-fertilization. Papers
focused on formal methods are especially welcome. Authors are invited to submit
original research or tool papers on all relevant topics in these areas. Papers
discussing new ideas that are at an early stage of development are also
welcome. The topics covered by the conference include, but are not limited to,
the following:
- Automata Theory
- Automated Deduction
- Computational aspects of Game Theory
- Concurrency and Distributed computation
- Decision Procedures
- Deductive, Compositional, and Abstraction Techniques for Verification
- Finite Model Theory
- First-order and Higher-order Logics
- Formal Languages
- Formal Methods for Systems Biology, Hybrid, Embedded, and Mobile Systems
- Games and Automata for Verification
- Game Semantics
- Logical aspects of Computational Complexity
- Logics of Programs
- Modal and Temporal Logics
- Model Checking
- Models of Reactive and Real-Time Systems
- Probabilistic Models (Markov Decision processes)
- Program Analysis and Software Verification
- Reinforcement Learning
- Run-time Verification and Testing
- Specification and Verification of Finite and Infinite-state Systems
- Synthesis

# Publications

The proceedings will be published by Electronic Proceedings in Theoretical
Computer Science. ***Authors of the best papers will be invited to submit a
revised version of their work to a special issue of Logical Methods in Computer
Science***. The previous editions of GandALF already led to special issues of
the International Journal of Foundations of Computer Science (GandALF 2010),
Theoretical Computer Science (GandALF 2011 and 2012), Information and
Computation (GandALF 2013, 2014, 2016, 2017, 2019 and 2020), and Acta
Informatica (GandALF 2015). Submissions Submitted papers should not exceed 14
pages (excluding references and clearly marked appendices) using EPTCS format,
be unpublished and contain original research. Please use the LaTeX style
provided at http://style.eptcs.org to format the paper. For papers reporting
experimental results, authors are encouraged to make their data available with
their submission. Submissions must be in PDF format and will be handled via the
EasyChair Conference system at the following address:
https://www.easychair.org/conferences/?conf=gandalf2021
