Maximum no. of nodes in a B-tree : ∑ from i=0 to h-1 of (n+1)^i = 1/n * ( (n+1)^h -1). This is the case as, each node can have a max. of n keys, then it will have a max. of n+1 children. So then summing up the max. no. of children from the root till the level h-1, gives the total no. of nodes possible in a B-tree.
Since each node has a max. of k-keys then, Max. no. of keys in a B-tree = n * 1/n * ((n+1)^h -1) = *(n+1)^h - 1* On Tue, Nov 20, 2012 at 11:14 AM, Sonu <sonuindi...@gmail.com> wrote: > Whats the formula used here?
