An inductive view of graph transformation
The dynamic behavior of rule-based systems (like term rewriting systems 24], process algebras 27], and so on) can be traditionally determined in two orthogonal ways. Either operati...

Graph Folding: Extending Detail and Context Viewing into a Tool for Subgraph Comparisons
It is a di cult problem to display large, complex graphs in a manner which furthers comprehension. A useful approach is to expand selected sections foci of the graph revealing de...

Local PTAS for Independent Set and Vertex Cover in Location Aware Unit Disk Graphs
We present the first local approximation schemes for maximum independent set and minimum vertex cover in unit disk graphs. In the graph model we assume that each node knows its geo...

Dagma: Mining Directed Acyclic Graphs
We present how to efficiently mine a set of directed acyclic graphs (DAGs) for unconnected, both multi- or single-rooted, and induced fragments. With a new canonical form that is ...

Minimising buffer requirements of synchronous dataflow graphs with model checking
Signal processing and multimedia applications are often implemented on resource constrained embedded systems. It is therefore important to find implementations that use as little ...
