消息传递算法在解决稀疏随机图上的硬约束满足问题方面取得了惊人的成功。在这种应用中,变量是按顺序固定的,以满足约束条件。消息传递在每一步之后运行。其结果为下一步的选择提供了启发式。这种方法被称为“抽取”,指的是统计物理学中的类似程序。人们对抽取程序的行为知之甚少。本文研究了一种简单的基于信念传播的随机抽取算法,并分析了该算法在随机K-可满足性公式上的性能。特别地,我们提出了一个树模型来分析它,我们猜想它在大实例的限制下提供了渐近精确的预测。数值模拟证实了这一猜想。

二级分类:Computational Complexity        计算复杂度
分类描述:Covers models of computation, complexity classes, structural complexity, complexity tradeoffs, upper and lower bounds. Roughly includes material in ACM Subject Classes F.1 (computation by abstract devices), F.2.3 (tradeoffs among complexity measures), and F.4.3 (formal languages), although some material in formal languages may be more appropriate for Logic in Computer Science. Some material in F.2.1 and F.2.2, may also be appropriate here, but is more likely to have Data Structures and Algorithms as the primary subject area.

英文摘要:
  Message passing algorithms have proved surprisingly successful in solving hard constraint satisfaction problems on sparse random graphs. In such applications, variables are fixed sequentially to satisfy the constraints. Message passing is run after each step. Its outcome provides an heuristic to make choices at next step. This approach has been referred to as `decimation,' with reference to analogous procedures in statistical physics.   The behavior of decimation procedures is poorly understood. Here we consider a simple randomized decimation algorithm based on belief propagation (BP), and analyze its behavior on random k-satisfiability formulae. In particular, we propose a tree model for its analysis and we conjecture that it provides asymptotically exact predictions in the limit of large instances. This conjecture is confirmed by numerical simulations.
