Determining computational complexity from characteristic 'phase transitions.'

Article Abstract:

It has been possible to establish the nature of the connection between phase transition phenomena and typical-case computational complexity. This research indicates that when the underlying computational task has a continuous ('second order') phase transition, resource requirements increase only polynomially with problem size. Techniques from statistical physics can give significant new information about computational phenomena. There is a need for greater understanding of the structure of phase transitions taking place in computational problems.
