摘要
We study the finite temperature statistical mechanics of Hamiltonian paths between a set of N quenched randomly distributed points in a finite domain D. The energy of the path is a function of the distance between neighbouring points on the path; an example is the travelling salesman problem where the energy is the total distance between neighbouring points on the path. We show how the system can be analysed in the limit of large N without using the replica method.
