Brute Force Determinization of NFAs by Means of State Covers
Finite automata determinization is a critical operation for numerous practical applications such as regular expression search. Algorithms have to deal with the possible blow up of ...

Detecting Backdoor Sets with Respect to Horn and Binary Clauses
We study the parameterized complexity of detecting backdoor sets for instances of the propositional satisfiability problem (SAT) with respect to the polynomially solvable classes ...

Dynamic Neighbourhood Cellular Automata
We propose a defi nition of Cellular Automaton in which links between cells can change during the computation. This is done locally by each cell, which can reach the neighbours of...

How to Securely Outsource Cryptographic Computations
We address the problem of using untrusted (potentially malicious) cryptographic helpers. We provide a formal security definition for securely outsourcing computations from a comp...

A Kernighan-Lin Local Improvement Heuristic That Solves Some Hard Problems in Genetic Algorithms
We present a Kernighan-Lin style local improvement heuristic for genetic algorithms. We analyze the run-time cost of the heuristic. We demonstrate through experiments that the heur...
