摘要: Phase transition is an important feature of SAT problem. For randomk-SAT model, it proved that asr (ratio clauses to variables) increases, the structure solutions will undergo a sudden change like satisfiability phase whenr reaches threshold point (r=r σ ). This phenomenon shows satisfying truth assignments suddenly shift from being relatively different each other very similar other.
