要旨:
The RAM complexity of deterministic linear space sorting of
integers in words is improved from $O(n\sqrt{\log n})$ to
$O(n(\log\log n)^2)$. No better
bounds are known for polynomial space. In fact, the techniques give a
deterministic linear space priority queue supporting insert and delete in
$O((\log\log n)^2)$ amortized time and find-min in constant time. The priority
queue can be implemented using addition, shift, and
bit-wise boolean operations.
