1 Spin Glass Cavity Method in Random K-Satisfiability Problem
Ma Hui

2 Random K-Satisfiability Problem

3 Structure of Solution Space changes as the constraint density increases

4 The Communities in a Single Solution Cluster
Haijun Zhou, Hui Ma, Communities of solutions in Single Solution Clusters of a Random K-Satisfiability Formula, Phys. Rev. E Accepted 12Nov,2009

5 From SAT to Max-SAT

6 Replica Symmetry Equations and Its Stability Analysis
Method for Replica Symmetry method: 1.Deviation of two replicas 2.Convergence of the belief propagation 3.Numerical instability towards 1RSB(m=1) solutions

7 The Threshold Temperature: Td &Trs

8 1RSB scenario

9 1RSB Stability Analysis
Two kinds of Stability 1. Iteration Stability 2.Stability to Bug proliferation

10 The Sample figure for Bug Proliferation

11 Thanks
