History-deterministic Vector Addition Systems
Sougata Bose, David Purser, Patrick Totzke
We consider history-determinism, a restricted form of non-determinism, for Vector Addition Systems with States (VASS) when used as acceptors to recognise languages of finite words.…
History-deterministic Timed Automata
Sougata Bose, Thomas A. Henzinger, Karoliina Lehtinen +2
We explore the notion of history-determinism in the context of timed automata (TA) over infinite timed words. History-deterministic (HD) automata are those in which nondeterminism…
One-way resynchronizability of word transducers
Sougata Bose, S. N. Krishna, Anca Muscholl +1
The origin semantics for transducers was proposed in 2014, and led to various characterizations and decidability results that are in contrast with the classical semantics. In this…
On Synthesis of Resynchronizers for Transducers
Sougata Bose, Shankara Narayanan Krishna, Anca Muscholl +2
We study two formalisms that allow to compare transducers over words under origin semantics: rational and regular resynchronizers, and show that the former are captured by the latt…
Origin-equivalence of two-way word transducers is in PSPACE
Sougata Bose, Anca Muscholl, Vincent Penelle +1
We consider equivalence and containment problems for word transductions. These problems are known to be undecidable when the transductions are relations between words realized by n…
