We study the phase diagram and the algorithmic hardness of the random 'locked' constraint satisfaction problems, and compare them to the commonly studied 'non-locked' problems like satisfiability of Bo... 详细信息

On the properties of the Bethe approximation and loopy belief propagation on binary networks

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2005年 第11期2005卷 P11012-P11012页
作者: Mooij, JM Kappen, HJ Radboud Univ Nijmegen Inst Neurosci Dept Biophys NL-6525 EZ Nijmegen Netherlands
We analyse the local stability of the high-temperature fixed point of the loopy belief propagation (LBP) algorithm and how this relates to the properties of the Bethe free energy which LBP tries to minimize. We focus ... 详细信息
