data structures - Understanding Fusion Trees? -

-

i stumbled across wikipedia page them:

fusion tree

and read class notes pdfs linked @ bottom, gets hand-wavy data structure , goes lot of detail sketch(x) function. think part of confusion papers trying general, , specific example visualize.

is data structure appropriate storing data based on arbitrary 32 or 64 bit integer keys? how differ b-tree? there 1 section says it's b-tree branching factor b = (lg n)^(1/5). populated tree 32 bit keys, b 2. become binary tree? data structure intended use longer bit-strings keys?

my googling didn't turn terribly useful, welcome links on topic. passing curiosity, haven't been willing pay pdfs @ portal.acm.org yet.

i've read (just quick pass) seminal paper , seems interesting. answers of questions in first page.

you may download paper here

hth!
