Odometers on Regular Languages
Odometers or “adding machines” are usually introduced in the context of positional numeration systems built on a strictly increasing sequence of integers. We generalize this no...

Networks of Evolutionary Processors with Subregular Filters
In this paper we propose a hierarchy of classes of languages, generated by networks of evolutionary processors with the filters in several special classes of regular sets. More p...

Classifying Regular Languages via Cascade Products of Automata
Abstract. Building on the celebrated Krohn-Rhodes Theorem we characterize classes of regular languages in terms of the cascade decompositions of minimal DFA of languages in those c...

Quotient Complexity of Regular Languages
The past research on the state complexity of operations on regular languages is examined, and a new approach based on an old method (derivatives of regular expressions) is presente...
