When a little nondeterminism goes a long way: An introduction to history-determinism
U Boker, K Lehtinen - ACM SIGLOG News, 2023 - dl.acm.org
History-deterministic automata are an intermediate automata model, in between
deterministic and nondeterministic ones. An automaton is history-deterministic if its …

On the size of good-for-games Rabin automata and its link with the memory in Muller games
A Casares, T Colcombet, K Lehtinen - arXiv preprint arXiv:2204.11333, 2022 - arxiv.org
In this paper, we look at good-for-games Rabin automata that recognise a Muller language
(a language that is entirely characterised by the set of letters that appear infinitely often in …

History-deterministic parikh automata
Parikh automata extend finite automata by counters that can be tested for membership in a
semilinear set, but only at the end of a run. Thereby, they preserve many of the desirable …

History-deterministic timed automata
We explore the notion of history-determinism in the context of timed automata (TA).
Historydeterministic automata are those in which nondeterminism can be resolved on the fly …

Checking History-Determinism is NP-hard for Parity Automata
A Prakash - International Conference on Foundations of Software …, 2024 - Springer
We show that the problem of checking if a given nondeterministic parity automaton simulates
another given nondeterministic parity automaton is NP-hard. We then adapt the techniques …
