Translation of binary regular expression
✍ Viliam Geffert πŸ“‚ Article πŸ“… 2003 πŸ› Elsevier Science 🌐 English βš– 281 KB

We show that every regular expression of size n over a fixed alphabet of s symbols can be converted into a nondeterministic e-free finite-state automaton with Oðsn log nÞ transitions (edges). In case of binary regular languages, this improves the previous known conversion from Oðnðlog nÞ 2 Þ transit

Log-space constructible universal traver
✍ Michal KouckΓ½ πŸ“‚ Article πŸ“… 2003 πŸ› Elsevier Science 🌐 English βš– 268 KB

The paper presents a simple construction of polynomial length universal traversal sequences for cycles. These universal traversal sequences are log-space (even NC 1 ) constructible and are of length O(n 4:03 ). Our result improves the previously known upper-bound O(n 4:76 ) for log-space constructib
