定性空间推理的有效方法

Efficient Methods for Qualitative Spatial Reasoning

B. Nebel, J. Renz

摘要:

在RCC 8框架下,定性空间推理的理论特性得到了广泛的分析。然而,尚未进行实证研究。我们的实验表明,用于定性时间推理的算法的自适应可以解决大的RCC 8实例,即使它们是在相变区域-只要一个使用的RCC 8已被我们确定的最大听话的子集。特别是,我们证明了正交组合的探试法是成功地解决了几乎所有显然很难的情况下,在相变区达到一定的规模在合理的时间。

英文摘要:

The theoretical properties of qualitative spatial reasoning in the RCC8 framework have been analyzed extensively. However, no empirical investigation has been made yet. Our experiments show that the adaption of the algorithms used for qualitative temporal reasoning can solve large RCC8 instances, even if they are in the phase transition region -- provided that one uses the maximal tractable subsets of RCC8 that have been identified by us. In particular, we demonstrate that the orthogonal combination of heuristic methods is successful in solving almost all apparently hard instances in the phase transition region up to a certain size in reasonable time.
