Cache-Oblivious Dynamic Search Trees Zardosht Kasheff
... B. Each node of size B holds as many pairs of keys and pointers as it may. The B-tree has uniform depth and is nearly balanced. Traversing an edge down the tree reduces the search space by a factor proportional to 1/B. Thus, B-trees perform data searches in Θ(1 + logB N ) memory transfers. An inform ...

We can use rr enclose to compute LCAs in a BPS S[0, 2n − 1] as follows: given two nodes i < j (we identify nodes with the position of their opening parenthesis), first compute k = rr enclose(S, i, j). Now if k 6= ⊥, return enclose(S, k) as LCA(i, j). The other possibility is that k = ⊥, which happen ...
