Adding regular expressions to graph reachability and pattern queries
—It is increasingly common to find graphs in which edges bear different types, indicating a variety of relationships. For such graphs we propose a class of reachability queries ...

Graph Pattern Matching: From Intractable to Polynomial Time
Graph pattern matching is typically defined in terms of subgraph isomorphism, which makes it an np-complete problem. Moreover, it requires bijective functions, which are often to...

Adaptive Graph Pattern Matching for Model Transformations using Model-sensitive Search Plans
The current paper makes two contributions for the graph pattern matching problem of model transformation tools. First, model-sensitive search plan generation is proposed for patte...
