Acta Informatica provides international dissemination of articles on formal methods for the design and analysis of programs, computing systems and information structures, as well as related fields of Theoretical Computer Science such as Automata Theory, Logic in Computer Science, and Algorithmics.Topics of interest include: semantics of programming languages models and modeling languages for concurrent, distributed, reactive and mobile systems models and modeling languages for timed, hybrid and probabilistic systems specification, program analysis and verification model checking and theorem proving modal, temporal, first- and higher-order logics, and their variants constraint logic, SAT/SMT-solving techniques theoretical aspects of databases, semi-structured data and finite model theory theoretical aspects of artificial intelligence, knowledge representation, description logic automata theory, formal languages, term and graph rewriting game-based models, synthesis type theory, typed calculi algebraic, coalgebraic and categorical methods formal aspects of performance, dependability and reliability analysis foundations of information and network security parallel, distributed and randomized algorithms design and analysis of algorithms foundations of network and communication protocols.
