Given a graph with edge weights and an integer k find a simple cycle of minimum weight visiting exactly k nodes. To obtain lower bounds for the traveling salesman problem the 2-matching relaxation and the 1-tree relaxation can be used.

Possible objective functions include minimizing the makespan k-Traveling Salesman Problem and minimizing the sum of completion times k-Traveling Repairman Problem. 07072020 The quota traveling salesman problem QTSP is a special case of the PCTSP where there is no penalty for not visiting a city ie penalties for all cities can be considered as zero. We consider the k-traveling repairmen problem also known as the minimum latency problem to multiple repairmen.
