In this paper we investigate the periodic structure of rich words (i.e., words having the highest possible number of palindromic factors), giving new results relating them with per...
Given a simple polygon in the plane with two distinguished vertices, s and g, is it possible for two guards to simultaneously walk along the two boundary chains from s to g in suc...
In this paper, we study the application of universal hashingto the construction of unconditionally secure authentication codes without secrecy. This idea is most useful when the nu...
Narrowing provides a complete procedure to solve equations modulo confluent and terminating rewriting systems. But it seldom terminates. This paper presents a method to improve th...
