Reachability Problems 15th International Conference, RP 2021, Liverpool, UK, October 25–27, 2021, Proceedings

This book constitutes the refereed proceedings of the 15th International Conference on Reachability Problems, RP 2021, held in Liverpool, UK in October 2021.

The 6 full papers presented were carefully reviewed and selected from 27 submissions. In addition, 4 invited papers were included in this volume. The RP proceedings cover topics such as reachability for infinite state systems; rewriting systems; reachability analysis in counter/timed/cellular/communicating automata; Petri nets; computational aspects of semigroups, groups, and rings; reachability in dynamical and hybrid systems; frontiers between decidable and undecidable reachability problems; complexity and decidability aspects; predictability in iterative maps; and new computational paradigms.
