Pattern Matching with Swaps (PMS for short) is a variation of the classical pattern matching problem where a match is allowed to include disjoint local swaps. In 2009, Cantone and Faro devised a new dynamic programming algorithm for PMS, named Cross-Sampling, that runs in O(nm) time and uses O(m) space. More important, Cross-Sampling admits a lineartime implementation based on bit parallelism when...
This paper revisits the notion of the sophistication of a string as adapted for finite strings based on prefix Kolmogorov complexity by Antunes and Fortnow. We propose a variant of sophistication that depends on the coarse graining (level of detail) at which the string is described. Then, we use the idea behind the self-dissimilarity complexity measure of Wolpert and Macready to propose new ways for...
A well known characterization of regular languages is provided by Nerode's Theorem. However, the pumping lemma is often a more useful tool in demonstrating properties of regular languages. In this paper, we rewrite an early pumping characterization of regular languages due to Stanat and Weiss so that some extra condition is made explicit in the theorem. This should allow for writing simpler proofs...
