Efficient Data Structures for Range-Aggregate Queries on Trees
tree is an ordered, rooted tree whose nodes have labels from an alphabet ? of size |?| = ?. We consider the following kinds of redundancy in the tree structure.
Module 8: Trees and Graphs - Purdue Computer ScienceA tree with n nodes has n -1 edges. Proof. Every node except the root has exactly one in-coming edge. Since there are n-1 nodes other than the root ... Tree decompositions and social graphs - UC Berkeley StatisticsOur main contributions are the following: we show that TD methods can identify structures that correlate strongly with the core-periphery ... Tree compression with top trees - DTU OrbitTheorem 1 Let T be any ordered tree with nodes labeled from an alphabet of size ? and let T D be the corresponding top DAG. Then, nT D ? OpnT {log. 0.19 ?. nT ...
