- 摘要： Dijkstra算法是目前公认的较好的最短路径算法。由于多点路由问题最终归结为最短路径问题,因此将算法改进后应用于多点路由问题。提出的改进主要有以下3点:(1)改变选路策略,基于蚁群算法实现Dijkstra算法的选路操作,使选路更加灵活。(2)结合网络模型的特点,减少了对两顶点之间最短路径以外的大量

- 摘要： 实现了一种基于模拟后缀数组的索引的结构,并在实现索引功能的同时对索引结构进行有效压缩。首先,对传统的哈夫曼编码压缩小波树时出现的空白编码进行了处理,应用正则哈夫曼编码有效的去掉了空白编码;其次,通过相关函数操作在已压缩的小波树上模拟实现了后缀数组功能。理论分析和实验结果表明,这种结构具有很小的空间占
