Query: Uniform Linked Lists Contraction   We present a parallel algorithm (EREW PRAM algorithm) for linked lists
contraction. We show that when we contract a linked list from size $n$ to size
$n/c$ for a suitable constant $c$ we can pack the linked list into an array of
size $n/d$ for a constant $1 < d\leq c$ in the time of 3 coloring the list.
Thus for a set of linked lists with a total of $n$ elements and the longest
list has $l$ elements our algorithm contracts them in $O(n\log
i/p+(\log^{(i)}n+\log i )\log \log l+ \log l)$ time, for an arbitrary
constructible integer $i$, with $p$ processors on the EREW PRAM, where
$\log^{(1)} n =\log n$ and $\log^{(t)}n=\log \log^{(t-1)} n$ and $\log^*n=\min
\{ i|\log^{(i)} n < 10\}$. When $i$ is a constant we get time
$O(n/p+\log^{(i)}n\log \log l+\log l)$. Thus when $l=\Omega (\log^{(c)}n)$ for
any constant $c$ we achieve $O(n/p+\log l)$ time. The previous best
deterministic EREW PRAM algorithm has time $O(n/p+\log n)$ and best CRCW PRAM
algorithm has time $O(n/p+\log n/\log \log n+\log l)$.
