摘要翻译：
我们开发了几个算法，利用了两种常见的方法来限定图形模型中的MPE查询：小桶消除和线性规划松弛的消息传递更新。这两种方法非常相似，并为另一种方法提供了有用的视角；我们的混合方法试图平衡每种方法的优势。我们通过大量的经验评估证明了我们的混合算法的能力。最值得注意的是，由我们的一个新算法计算的启发式函数引导的分支定界搜索最近在PASCAL2推理挑战赛中获得了第一名。

英文摘要：
We develop several algorithms taking advantage of two common approaches for bounding MPE queries in graphical models: minibucket elimination and message-passing updates for linear programming relaxations. Both methods are quite similar, and offer useful perspectives for the other; our hybrid approaches attempt to balance the advantages of each. We demonstrate the power of our hybrid algorithms through extensive empirical evaluation. Most notably, a Branch and Bound search guided by the heuristic function calculated by one of our new algorithms has recently won first place in the PASCAL2 inference challenge.
