The paper describes a new algorithm to produce r-optimal tours for the travelling salesman problem. This algorithm is faster than the original r-optimal method, and computation times increase much ...

This paper presents a constraint logic programming model for the traveling salesman problem with time windows which yields an exact branch-and-bound optimization algorithm without any restrictive ...

The most efficient path that visits each of 2 million stars just once We have found the best path to take between the stars. The travelling salesman problem, an infamous mathematical puzzle that ...
