Research Type Theoretical We investigate the following many-to-one stable matching problem with diversity constraints (SMTI-DIVERSE)... SMTI-DIVERSE is known to be NP-hard. However, as opposed to the NP-membership claims in the literature [Aziz et al., 2019; Huang, 2010], we prove that it is beyond NP: it is complete for the complexity class ΣP 2. In addition, we provide a comprehensive analysis of the problem s complexity from the viewpoint of natural restrictions to inputs and obtain new algorithms for the problem.
