Simple Rank/Select Dictionaries

Abstract (in Japanese) (See Japanese page) 
(in English) Rank/Select directories are data structures to compute,for an ordered set S ⊂{0 , 1 ,...,m −1 },
rank x, S = |{y ∈S |y < =x }|)and select i, S (the i th smallest element in S .These are basic components of
succinct data structures to store strings,trees,graphs,etc.,and many data structures for them have been proposed.
However,in those data structures only asymptotic behavior is considered and their performance for real data is not
satisfactory.In this paper,we propose simple Rank/Select directories.Advantages of them are:(1)the size of the
data structure is small if the number of elements in S is small,(2)the data structure is simple,thus the performance
for real data is superior in terms of size and query time.Experimental results show our data structure is superior to
existing implementations in both size and query time.
