The traveling salesman problem: An update of research
TLDR
This article presents a review of attacks on the traveling salesman problem for problems defined on weighted and unweighted graphs and includes some aspects of nonexact algorithms with major interest confined to the establishment of worst-case bounds.

Some Simple Applications of the Travelling Salesman Problem
TLDR
This paper reports on typical applications in computer wiring, vehicle routing, clustering and job-shop scheduling that originated from real world problems and thus seem to be of particular interest.
The adjacency relation on the traveling salesman polytope is NP-Complete
TLDR
This problem of determining whether two traveling salesman tours correspond to non-adjacent vertices of the convex polytope associated with the traveling salesman problem is shown to be NP-Complete for both the symmetric and nonsymmetric traveled salesman problem.
