The Travelling Salesman Problem with Pickups and Deliveries (TSPPD) consists in designing a minimum cost tour that starts at the depot, provides either a pickup or delivery service to each of the ...

We report the solution to optimality of ten large-scale symmetric travelling salesman problems. The travelling salesman problem (TSP) is one of the standard problems of the Operations ...

The travelling salesman problem (TSP) remains one of the most challenging NP‐hard problems in combinatorial optimisation, with significant implications for logistics, network design and route ...

After Karp’s paper was published, many computer scientists set their sights on creating an efficient algorithm to find approximate solutions to the traveling salesman problem — round-trip ...

The traveling salesman problem is one of the basic problems that many theoretical computer scientists have been working on. Many scientists think that there is no algorithm for the traveling ...

This is a problem that has stumped mathematicians for decades, and there is even a prize for anyone who can come up with an algorithm to solve it.

A new algorithm which could provide a solution to the age old Traveling Salesman Problem (TSP) has been improved by a student.

The travelling salesman problem seems simple, but it is notoriously difficult. It can be solved for specific data sets, but a general algorithm to solve any instance of the problem hasn’t yet ...
