具有连通性谓词的空间逻辑

Spatial logics with connectedness predicates

Roman Kontchakov, Ian Pratt-Hartmann, Frank Wolter, Michael Zakharyaschev

摘要:

我们考虑量化器自由空间逻辑,设计用于定性空间表示和推理在AI中,并扩展它们的手段来表示区域的拓扑连通性和限制其连接组件的数量。我们调查这些逻辑的计算复杂性,并表明,连接性约束可以增加复杂性从NP到PSpace,ExpTime,如果组件计数是允许的,NExpTime。

英文摘要:

We consider quantifier-free spatial logics, designed for qualitative spatial representation and reasoning in AI, and extend them with the means to represent topological connectedness of regions and restrict the number of their connected components. We investigate the computational complexity of these logics and show that the connectedness constraints can increase complexity from NP to PSpace, ExpTime and, if component counting is allowed, to NExpTime.
