... algorithm they gave two node splitting algorithms. The first one is a basic node splitting algorithm which partitions a full node into two making a metric the best. The second algorithm is an improvement of the basic one, called SHIFT method, to gain a high occupancy of disk pages. The metrics used ...

Graphs and Graph Algorithms
... A subgraph of a graph G , is a graph whose nodes and edges are a subset of those of G and whose edges have the same source and target as those of G . A connected component (sometimes, just a ‘component’) of a graph G , is a largest connected subgraph (i.e. one that cannot be expanded with additional ...

Efficient Substructure Discovery from Large Semi
... The depth of T is the length of the longest path from the root to some leaf in T . In Fig. 1, we show examples of labeled ordered trees, say D and T , on the alphabet L = {A, B}, where a circle with the number, say v, at its upper right corner indicates the node v, and the symbol appearing in a circ ...
