Contextual insertions/deletions and computability

L Kari, G Thierrin - Information and computation, 1996 - Elsevier
We investigate two generalizations of insertion and deletion of words, that have recently
become of interest in the context of molecular computing. Given a pair of words (x, y), called …

Beginning with an informal introduction to language equations, this book presents a
framework for a general theory for solving systems of equations and relations between …

What do we know about language equations?

M Kunc - … Conference on Developments in Language Theory, 2007 - Springer
In the talk we give an overview of recent developments in the area of language equations,
with an emphasis on methods for dealing with non-classical types of equations whose …

Component-based design by solving language equations

T Villa, A Petrenko, N Yevtushenko… - Proceedings of the …, 2015 - ieeexplore.ieee.org
An important step in the design of a complex system is its decomposition into a number of

Decision problems for language equations

A Okhotin - Journal of Computer and System Sciences, 2010 - Elsevier
Equations with formal languages as unknowns using all Boolean operations and
concatenation are studied. Their main properties, such as solution existence and …

Deletion along trajectories

M Domaratzki - Theoretical Computer Science, 2004 - Elsevier
We describe a new way to model deletion operations on formal languages, called deletion
along trajectories. We examine its closure properties, which differ from those of shuffle on …

L Kari, S Konstantinidis, P Sosík - International Journal of …, 2005 - World Scientific
The problem of negative design of DNA languages is addressed, that is, properties and
construction methods of large sets of words that prevent undesired bonds when used in …

Closure and decidability properties of some language classes with respect to ciliate bio-operations

M Daley, OH Ibarra, L Kari - Theoretical Computer Science, 2003 - Elsevier
The process of gene unscrambling in ciliates (a type of unicellular protozoa), which

On properties of bond-free DNA languages

L Kari, S Konstantinidis, P Sosík - Theoretical Computer Science, 2005 - Elsevier
The input data for DNA computing must be encoded into the form of single or double DNA
strands. As complementary parts of single strands can bind together forming a double …
