摘要翻译：
本文提出了一种度量方法来限制和/或搜索算法的性能，以解决图形模型上的各种查询。我们展示了如何与最近的超树分解概念建立联系，从而利用问题说明中的决定论，并产生更严格的界限。我们在各种实际问题实例上证明，我们经常能够在现有的界限上提高几个数量级。

英文摘要：
This paper develops a measure for bounding the performance of AND/OR search algorithms for solving a variety of queries over graphical models. We show how drawing a connection to the recent notion of hypertree decompositions allows to exploit determinism in the problem specification and produce tighter bounds. We demonstrate on a variety of practical problem instances that we are often able to improve upon existing bounds by several orders of magnitude.
