The aim of the research group is to develop new, nonconventional
computational models and to study their properties, their
applicability in different areas of computer science. This approach
can be justified, on one hand, by the intention of inventing
computational paradigms for the efficient use of the new possibilities
offered by modern technology, and on the other hand, by the hope of a
better and more precise understanding of the structure, functioning,
and behavior of living systems and their communities, certain
processes going on in nature, or social, cultural phenomena appearing
in our society.
The two main areas of the investigations are
nature-motivated computational models,
with particular focus on distributed architectures
described in a formal language theoretical
framework, such as membrane systems (P
systems) or DNA-inspired architectures, and
formal language theoretic paradigms of
multi-agent systems, that is, different variants
of grammar systems.
The members of the group have fundamental contributions
to both areas, which includes introductions
of formal descriptions of fundamental notions
and important properties of different kinds
of multi-agent systems (cooperative and distributed
problem solving systems, simple reactive systems,
ecosystems, knowledge networks) and new
important concepts in the theory of membrane
systems and molecular computing.
Erzsébet Csuhaj-Varjú, D.Sc., Ph.D, Dr. habil, science
advisor, head of the group.
She is is also full professor at
the Department of Algorithms and Applications of the Eötvös Loránd
University, Budapest. Her main research interests are formal
languages, distributed systems and bio-inspired computing. In these
areas she (herself or with co-authors) published over 170 articles in
international journals and edited volumes, a monograph and edited 14
volumes. Her publications have so far received over 750 citations. She
has been co-founder of the area of grammars systems, a formal
languagetheoretic counterpart of the theory of multi-agent
systems. She has important contributions to molecular computing and
membrane computing. She and György Vaszil are
co-founders of the area of P automata in the theory of P systems,
i.e., membrane systems.
She is and she was supervisor (principal investigator) and participant
of several Hungarian and bilateral granted research projects, team
leader of EU projects. She is the Hungarian team leader of the
European Molecular Computing Consortium. She is a member of the
editorial board of ERCIM NEWS, the quarterly of the European Research
Consortium for Informatics and Mathematics and the International
Journal of Foundations of Computer Science. In the last five years,
she has been program committee chair, co-chair, program committee
member and organizer of over 35 international workshops and
conferences, among them conferences and workshops in bio-inspired
She has been supervisor of Hungarian and foreign visiting PhD students
and postdoctoral fellowship holders. She is regular reviewer of
Hungarian and foreign grant agencies, including ERC.
György Vaszil, Ph.D, senior research fellow.
His main research fields of interest are bio-inspired computing,
formal language and automata theory, and distributed systems. He is
author or co-author of more than 70 scientific publications, editor or
coeditor of 5 edited volumes. His articles have so far received about
170 independent citations. He is cofounder of the subfield of P
automata, and he has significant contributions to the development of
grammar systems theory as well.
He was awarded with the Bolyai János post-doctoral research
scholarship by the Hungarian Academy of Sciences and the prestigeous
Alexander von Humboldt research scholarship. He was also working in
the Computer Science Department of the University of Potsdam as a
visiting researcher. He has been the participant of several national
and international research projects, and he was program committee
member or participated in the organization of several international
workshops or conferences. He has been regular reviewer of leading
international journals, grant agencies in Hungary and abroad.
