提出了一种使用O (n logn)个处理器的O (logn logn) CRCW PRAM算法,用于计算无界字母表上长度为n的字的唯一Lyndon分解;这改进了Apostolico和Crochemore(1989)给出的界。此外,在固定字母的情况下,CRCW PRAM算法是最优的(线性代价),需要O (log n)个单位时间。
An O (logn log log n) CRCW PRAM algorithm using O (n log n) processors for computing the unique Lyndon factorization of a word of length n over an unbounded alphabet is presented; this improves the bounds given by Apostolico and Crochemore (1989). Moreover, in the case of fixed alphabets the CRCW PRAM algorithm is optimal (linear cost), requiring O (log n) units of time.
