| 中文摘要: |
| 提出了谓词之间的一种相似关系,并用该相似关系得到可实现某谓词的动作集.利用该动作集中所有动作的公共前提谓词和公共效果谓词,提取出隐含在动作描述中的领域知识,并给出了描述领域知识的一种形式化方法.最后,对具体的规划问题,可利用领域知识判断出初始状态或目标状态中存在的矛盾.该领域知识的提取策略已应用于智能规划器StepByStep之中,所获取的领域知识对选择待实现的谓词提供了必要的理论依据. |
| 英文摘要: |
| In this paper, a similarity relation between two predicates is defined first. To a given predicate, the set of action for the predicate can be obtained by the similarity relation. Then, the domain knowledge is extracted from the common fluent in preconditions and effects of all actions for each set of action, and the formalism for the domain knowledge is given. Finally, the contradictions in the initial states and the goal states in a particular planning problem with domain knowledge can be discovered. The strategy of extracting the domain knowledge is integrated in the planner StepByStep, and the domain knowledge is the necessary theory when one predicate by action is realized in the planner. |
