On 2-SAT and Renamable Horn
We introduce new linear time algorithms for satisfiability of binary propositional theories (2-SAT), and for recognition and satisfiability of renamable Horn theories. The algorit...

Dominating Cliques in Distance-Hereditary Graphs
A graph is distance-hereditary if and only if each cycle on five or more vertices has at least two crossing chords. We present linear time algorithms for the minimum r-dominating c...

Finding Cores of Limited Length
In this paper we consider the problem of nding a core of limited length in a tree. A core is a path, which minimizes the sum of the distances to all nodes in the tree. This proble...
