Abstract

The Shortest Path problem is one of the classical combinatorial optimisation problems that has been extensively studied in the deterministic setting, where the arc weights are precisely known. While this model is often sufficient, real-world applications frequently involve uncertainty, limited control over input data, or a partitioning of decision variables among multiple decision makers. One of the approaches suitable in that setting is bilevel optimisation -- a framework in which the problem is divided into two hierarchically dependent subproblems.

In this work, we introduce a new problem: the Neighbourhood-Constrained Bilevel Shortest Path Problem (NCBSP), where the follower's decision space is restricted to the neighbourhood of the leader's decision. We present preliminary results on the computational complexity of the NCBSP and explore its relationships to other well-known optimisation problems.
