On the Complexity of Package Recommendation Problems
Summary: Formalize package recommendations: multi-criteria selection, compatibility constraints, and utility/cost functions; support query-relaxation and vendor-adjustment suggestions. Prove tight combined/data-complexity bounds for decision, counting and computation tasks for top-k packages, exposing effects of package size, compatibility, and query expressiveness.
