摘要

摘要

En 中文
We study the computational complexity of the qualitative algebra which is a temporal constraint formalism that combines the point algebra, the point-interval algebra and Allen's interval algebra. We identify all tractable fragments and show that every other fragment is NP-complete. (C) 2004 Elsevier B.V. All rights reserved.
