Comparing Hierarchical Data in External Memory
We present an external-memory algorithm for computing a minimum-cost edit script between two rooted, ordered, labeled trees. The I/O, RAM, and CPU costs of our algorithm are, resp...

A First Experimental Evaluation of Search Plan Driven Graph Pattern Matching
Abstract. With graph pattern matching the field of graph transformation (GT) includes an NP-complete subtask. But for real-life applications it is essential that graph pattern mat...
