The configuration of a feature subscription involves choosing and sequencing features from a catalogue and is subject to  constraints that prevent undesirable feature interactions at run-time. When the subscription requested by a user is inconsistent, one  problem is to find an optimal relaxation,  which is a generalisation of the feedback vertex  set problem on directed graphs, and thus it is an NP-hard task.
