摘要：
We consider the problem of finding an element of a given rank in a totally ordered set given in a read-only array, using Limited extra storage cells. We give new algorithms for various ranges of extra space. Our upper bounds improve the previously known bounds in the range of space s such that s is o(lg(2) n) and s greater than or equal to clg lg n/ lg lg lg n for some constant c. We also give faster algorithms to find small ranks.
