A Heterogeneous Pushout Approach to Term-Graph Transformation
We address the problem of cyclic termgraph rewriting. We propose a new framework where rewrite rules are tuples of the form (L, R, τ, σ) such that L and R are termgraphs represen...

Minimum Bounded Degree Spanning Trees
We consider the minimum cost spanning tree problem under the restriction that all degrees must be at most a given value k. We show that we can efficiently find a spanning tree o...

Flexible Exclusion Control for Composite Objects
We present a simple approach for implementing flexible locking strategies in a system of components, which may themselves be composite objects. The approach is flexible in that a ...

A Dichotomy Theorem for Constraints on a Three-Element Set
The Constraint Satisfaction Problem (CSP) provides a common framework for many combinatorial problems. The general CSP is known to be NP-complete; however, certain restrictions on...
