| 摘 要： | 摘要：为了兼顾全息句法规则的准确性和覆盖面，用递阶结构表达知识，用常量和变量相结合标注特征，归纳出一类相关对象组合匹配模型。针对模型在规则匹配搜索中的“组合爆炸”问题，提出一种基于相关对象解耦的递阶智能搜索方法。根据此方法，先用闭环消除法消去对象中不满足相关约束条件的数据，然后采用简单的顺序搜索获得问题解。这种方法从根本上避免了回溯，显著地减少了计算机在时间和空间上的开销。

| Abstract: | In order to talce into account both veracity and covering square of the holographic syntax rule,using a hierarchical model for knowledge expression and a combination of constants and variables for signing its characteristics,a kind of combinatorial matching model of correlated objects is induced.In allusion to the "combination blown-out" problem involving the model in rule matching search,a hierarchical intelligence search method based on decoupling the correlated objects is put forward.According to this me... |
