In Search Of Most Complex Regular Languages
(World Scientific Publishing, 2013-09-01)
Sequences (L-n vertical bar n >= k), called streams, of regular languages L-n are considered, where k is some small positive integer, n is the state complexity of L-n, and the languages in a stream differ only in the ...
Complexity Of Atoms Of Regular Languages
(World Scientific Publishing, 2013-11-01)
The quotient complexity of a regular language L, which is the same as its state complexity the number of left quotients of L. An atom of a non-empty regular language L with n quotients is a non-empty intersection of the n ...
Quotient Complexity of Bifix-, Factor-, and Subword-Free Regular Language
(Institute of Informatics: University of Szeged, 2014)
A language $L$ is prefix-free if whenever words $u$ and $v$ are in $L$ and $u$ is a prefix of $v$, then $u=v$. Suffix-, factor-, and subword-free languages are defined similarly, where by ``subword" we mean ``subsequence", ...
