Computing the edit distance of a regular language
The edit distance (or Levenshtein distance) between two words is the smallest number of substitutions, insertions, and deletions of symbols that can be used to transform one of the...

The Wadge Hierarchy of Max-Regular Languages
Recently, Mikołaj Boja´nczyk introduced a class of max-regular languages, an extension of regular languages of infinite words preserving many of its usual properties. This new c...

A proof Procedure for Testing Membership in Regular Expressions
We propose an algorithm that tests membership for regular expressions and show that the algorithm is correct. This algorithm is written in the style of a sequent proof system. The...

Simple Effective Decipherment via Combinatorial Optimization
We present a simple objective function that when optimized yields accurate solutions to both decipherment and cognate pair identification problems. The objective simultaneously s...
