Based on this index structure, a set of heuristic pruning rules is used, which greatly reduces the times of domination test. 基于该索引结构,进一步采用启发式剪枝策略,极大地降低了支配测试的次数。
These algorithms search the P/ S ( publication/ subscription) tree using a heuristic pruning method to discover object instances with high efficiency, and generate the sending templates to facilitate the reflection of attributes updating. 这些算法使用启发信息和剪枝条件搜索公布/订购树,生成发送模板,提高了发现对象的搜索效率和数据更新时的反射发送效率。
