20th International Conference on Reachability Problems

October 21-23 2026, Turku, Finland



Welcome to Turku!

About the conference

RP is specifically aimed at gathering together scholars from diverse disciplines and backgrounds
interested in reachability problems that appear in

  • Algebraic structures
  • Automata theory and formal languages
  • Computational game theory
  • Concurrency and distributed computation
  • Decision procedures in computational models
  • Hybrid systems
  • Logic and model checking
  • Verification of finite and infinite-state systems

Topics of interest include (but are not limited to): reachability problems in infinite-state systems, rewriting systems, dynamical and hybrid systems; reachability problems in logic and verification; reachability analysis in different computational models, counter timed/ cellular/communicating automata; Petri nets; computational and combinatorial aspects of algebraic structures (semigroups, groups and rings); frontiers between decidable and undecidable reachability problems; predictability in iterative maps and new computational paradigms.
