Computational Complexity of the Recoverable Robust Shortest Path Problem with Discrete Recourse (2403.20000v1)

Published 29 Mar 2024 in cs.CC

Abstract: In this paper the recoverable robust shortest path problem is investigated. Discrete budgeted interval uncertainty representation is used to model uncertain second-stage arc costs. The known complexity results for this problem are strengthened. It is shown that it is Sigma_3p-hard for the arc exclusion and the arc symmetric difference neighborhoods. Furthermore, it is also proven that the inner adversarial problem for these neighborhoods is Pi_2p-hard.
