中文摘要:
      为一个巨大的文本集合构造后缀数组是目前搜索引擎领域中的一个热点问题.对已存在的后缀数组的外存构造算法加以优化.优化后的算法仍然遵循原有方法的基本原则,但采用不同的实现策略,保证了算法在最坏情况下的较好的时间复杂度。
英文摘要:
      The construction of suffix on very large text collections is nowadays a hot problem within the domain of search engine. In this paper, we optimize the external-memory algorithm which is devised by Andreas Crause. The optimized algorithm follows the basic philosophy underlying that algorithm but in a different manner, thus resulting in a novel approach which achieves good worst-case time-bounds.
