JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2017年 第9期2017卷
作者: Colabrese, S. De Martino, D. Leuzzi, L. Marinari, E. Univ Tor Vergata Dip Fis I-00133 Rome Italy Inst Sci & Technol Austria IST Austria Campus 1 A-3400 Klosterneuburg Austria Natl Res Council Italy Inst Nanotechnol CNR NANOTEC Soft & Living Matter LabRome Unit Ple A Moro 5 I-00185 Rome Italy Sapienza Univ Roma Dipartimento Fis Ple A Moro 2 I-00815 Rome Italy INFN Sez Roma 1 Berkeley CA USA
The resolution of a linear system with positive integer variables is a basic yet difficult computational problem with many applications. We consider sparse uncorrelated random systems parametrised by the density c and... 详细信息

Random multi-index matching problems -: art. no. P09006
收藏 引用
JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2005年 第09期2005卷 P09006-P09006页
作者: Martin, OC Mézard, M Rivoire, O Univ Paris 11 Lab Phys Theor & Modeles Stat F-91405 Orsay France
The multi-index matching problem generalizes the well known matching problem by going from pairs to d-uplets. We use the cavity method from statistical physics to analyse its properties when the costs of the d-uplets ... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2024年 第1期2024卷 013403-013403页
作者: Erba, Vittorio Krzakala, Florent Perez Ortiz, Rodrigo Zdeborova, Lenka Ecole Polytech Fed Lausanne EPFL Stat Phys Computat Lab CH-1015 Lausanne Switzerland Ecole Polytech Fed Lausanne EPFL Informat Learning & Phys Lab CH-1015 Lausanne Switzerland
We study the maximum-average submatrix problem, wherein given an N x N matrix J, one needs to find the k x k submatrix with the largest average number of entries. We investigate the problem for random matrices J, whos... 详细信息

Constraint satisfaction problems with isolated solutions are hard

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2008年 第12期2008卷 P12004-P12004页
作者: Zdeborova, Lenka Mezard, Marc Univ Paris Sud LPTMS UMR8626 CNRS F-91405 Orsay France Los Alamos Natl Lab Div Theoret Los Alamos NM 87545 USA Los Alamos Natl Lab Ctr Nonlinear Studies Los Alamos NM 87545 USA
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

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2016年 第11期2016卷 113401-113401页
作者: Takabe, Satoshi Hukushima, Koji Univ Tokyo Grad Sch Arts & Sci Meguro Ku 3-8-1 Komaba Tokyo 1538902 Japan Natl Inst Mat Sci Ctr Mat Res Informat Integrat 1-2-1 Sengen Tsukuba Ibaraki 3050047 Japan
typical performance of approximation algorithms is studied for randomized minimum vertex cover problems. A wide class of random graph ensembles characterized by an arbitrary degree distribution is discussed with the p... 详细信息

Parallel complexity of random Boolean circuits

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2011年 第4期2011卷 P04015-P04015页
作者: Machta, J. DeDeo, S. Mertens, S. Moore, C. Santa Fe Inst Santa Fe NM 87501 USA Univ Massachusetts Dept Phys Amherst MA USA Otto Von Guericke Univ Inst Theoret Phys D-39106 Magdeburg Germany Univ New Mexico Dept Comp Sci Albuquerque NM 87131 USA Univ New Mexico Dept Phys & Astron Albuquerque NM 87131 USA
Random instances of feedforward Boolean circuits are studied both analytically and numerically. Evaluating these circuits is known to be a P-complete problem and thus, in the worst case, believed to be impossible to p... 详细信息

On the number of k-cycles in the assignment problem for random matrices
收藏 引用
JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2008年 第03期2008卷 P03019-P03019页
作者: Esteve, Jose G. Falceto, Fernando Univ Zaragoza Fac Ciencias Dept Fis Teor E-50009 Zaragoza Spain Univ Zaragoza Inst Biocomputac & Fis Sistemas Complejos E-50009 Zaragoza Spain
We continue the study of the assignment problem for a random cost matrix. We analyse the number of k-cycles for the solution and their dependence on the symmetry of the random matrix. We observe that for a symmetric m... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2013年 第4期2013卷 P04008-P04008页
作者: Chamon, Claudio Mucciolo, Eduardo R. Boston Univ Dept Phys Boston MA 02215 USA Univ Cent Florida Dept Phys Orlando FL 32816 USA
Counting problems such as determining how many bit strings satisfy a given Boolean logic formula are notoriously hard. In many cases, even getting an approximate count is difficult. Here we propose that entanglement, ... 详细信息

In this review article we discuss connections between the physics of disordered systems, phase transitions in inference problems, and computational hardness. We introduce two models representing the behavior of glassy... 详细信息
