: Work systems are complex artifacts that address the concerns of a large and diverse group of stakeholders. These concerns must be reflected in the models which are created as use...
We study the complexity of structurally restricted homomorphism and constraint satisfaction problems. For every class of relational structures C, let LHOM(C, _) be the problem of d...
Abstract. In this paper we analyze the complexity of checking safety and termination properties, for a very simple, yet non-trivial, class of programs with singly-linked list data ...
Modularity is a recently introduced quality measure for graph clusterings. It has immediately received considerable attention in several disciplines, and in particular in the compl...

Treewidth measures the ”tree-likeness” of structures. Many NP-complete problems, e.g., propositional satisfiability, are tractable on bounded-treewidth structures. In this wo...
