An Efficient Algorithm for Solving the Dyck-CFL Reachability Problem on Trees
The context-free language (CFL) reachability problem is well known and studied in computer science, as a fundamental problem underlying many important static analyses such as point...

The set constraint/CFL reachability connection in practice
Many program analyses can be reduced to graph reachability problems involving a limited form of context-free language reachability called Dyck-CFL reachability. We show a new redu...

Efficient data structures for range-aggregate queries on trees
Graph-theoretic aggregation problems have been considered both in OLAP (grid graph) and XML (tree). This paper gives new results for MIN aggregation in a tree, where we want the M...

A lookahead strategy for solving large planning problems
Relaxed plans are used in the heuristic search planner FF for computing a numerical heuristic and extracting helpful actions. We present a novel way for extracting information fro...
