JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2008年 第04期2008卷 P04004-P04004页
作者: Montanari, Andrea Ricci-Tersenghi, Federico Semerjian, Guilhem Stanford Univ Dept Elect Engn Stanford CA 94305 USA Stanford Univ Dept Stat Stanford CA 94305 USA Univ Roma La Sapienza Dipartimento Fis I-00185 Rome Italy Univ Roma La Sapienza CNR INFM I-00185 Rome Italy Univ Paris 06 CNRS UMR 8549 LPTENS F-75231 Paris 05 France Univ Paris 06 ENS Associee UPMC F-75231 Paris 05 France
We study the set of solutions of random k-satisfiability formulas through the cavity method. It is known that, for an interval of the clause-to-variables ratio, this decomposes into an exponential number of pure state... 详细信息
