Nested searching algorithm with fractal division interpolation and chaos optimization for optimal operation of cascade hydropower plants 梯级水电站优化调度的分形与混沌嵌套搜索算法
Filters that are nested deeper than the search stack depth will cause a separate stack to be allocated for that particular search operation. 过滤器嵌套深度比搜索堆栈深度更深将引起分配独立堆栈给特定的搜索选项。
Besides, we choose the improved nested loop join algorithm to deal with join operation in memory-constrained environment. 针对内存受限,采用了改进的嵌套循环连接算法。
The result integration algorithm mainly processes result sets in respects of connection operation, group operation and nested query; connection operation sorts the result sets using the technology of preprocessing, group operation grounds on balanced tree, nested query utilizes hash mapping and iterator. 结果整合算法主要对结果集进行连接操作、分组操作及嵌套查询;连接操作使用预处理技术对结果集进行排序,分组操作基于平衡树进行,嵌套查询利用Hash映射和迭代器完成。
