We define simple-regular expressions and languages. Simple-regular languages provide a necessary condition for a language to be outfix-free. We design algorithms that compute si...
We consider the use of state elimination to construct shorter regular expressions from finite-state automata. Although state elimination is an intuitive method for computing regul...
Automata-based representations and related algorithms have been applied to address several problems in information security, and often the automata had to be augmented with additi...
