2 00 1 Statistical mechanics methods and phase transitions in optimization problems
Recently, it has been recognized that phase transitions play an important role in the probabilistic analysis of combinatorial optimization problems. However, there are in fact many other relations that lead to close ties between computer science and statistical physics. This review aims at presenting the tools and concepts designed by physicists to deal with optimization or decision problems in...

متن کاملPhase Transitions and Backbones of the Asymmetric Traveling Salesman Problem
In recent years, there has been much interest in phase transitions of combinatorial problems. Phase transitions have been successfully used to analyze combinatorial optimization problems, characterize their typical-case features and locate the hardest problem instances. In this paper, we study phase transitions of the asymmetric Traveling Salesman Problem (ATSP), an NP-hard combinatorial optimi...
متن کاملPhase Transitions, Backbones and Heuristic Search
A phase transition refers to such a phenomenon of a system (or combinatorial problem) in which some global properties change rapidly and dramatically when a control parameter crosses a critical value. A simple example of phase transition is water changing phases from solid (ice) to liquid (water) to gas (steam) as the temperature increases. The backbone of a problem is the fraction of variables...
