This paper concerns finding a tight lower bound to the travelling-salesman problem, with the hope that all the different branch-and-bound algorithms for this problem can benefit from it. The bound is ...

Many algorithms have been developed for the optimal solution of the asymmetric travelling salesman problem: the most efficient ones are based on the subtour elimination approach. This paper presents a ...

A new approach to solving the ‘Travelling Salesperson Problem’ – one of the most difficult questions in computer science – significantly outperforms current approaches. A notorious theoretical ...
