Marc Goerigk and Stefan Lendl and Lasse Wulf
2021 arXiv   pre-print
In this paper we consider the Recoverable Traveling Salesman Problem (TSP).  ...  We discuss consequences for approximability results in the more general area of recoverable robust optimization.  ...  We also study a multi-stage generalization of RecovTSP which we call k-Stage Recoverable Traveling Salesman Problem (k-St-RecovTSP).  ...

On the recoverable robust traveling salesman problem

André Chassein, Marc Goerigk
2015 Optimization Letters  
We consider an uncertain traveling salesman problem, where distances between nodes are not known exactly, but may stem from an uncertainty set of possible scenarios.  ...  This uncertainty set is given as intervals with an additional bound on the number of distances that may deviate from their expected, nominal value.  ...  Introduction The traveling salesman problem (TSP) is one of the most researched NP-complete optimization problems in the operations research community (see, e.g., [LLKS85] ).  ...
