Although near-optimal algorithms have been proposed for this problem, practical concerns regarding scalability, compatibility with distributed implementation, and expensive oracle queries persist in large-scale applications. Motivated by online platforms that rely on individual item scores for content recommendation and team selection, we p","authors_text":"Milan Vojnovic, Se-Young Yun, Shreyas Sekar","cross_cats":["math.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-05-23T15:51:59Z","title":"Submodular Maximization using Test Scores"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.07172","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5a2607d7f930876d460b7b987c7887fc2f5e57a9bf6e72c4dfde8f7a593015a8","target":"record","created_at":"2026-05-17T23:46:42Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"9bc72d5522f0a64c6ce2c1f603354ad979f158d8c21f500c7c35b043bb94a147","cross_cats_sorted":["math.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-05-23T15:51:59Z","title_canon_sha256":"114eab1bacd3d950f1cdc20e6b5dc1137e80d30b2292d2632060b60600acfa4e"},"schema_version":"1.0","source":{"id":"1605.07172","kind":"arxiv","version":4}},"canonical_sha256":"1596067d1a61136311478be742e20f2108fc81e48a215be718c49ca5a11793da","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1596067d1a61136311478be742e20f2108fc81e48a215be718c49ca5a11793da","first_computed_at":"2026-05-17T23:46:42.260267Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:46:42.260267Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"s6a7dtWWJie0h4GhIqj+Zj0hR71BFKei22SVXgsVGSaMCwJh77wLeiQyE+oBhqhvA3lhxKurPHqsA5xbSodOCg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:46:42.260861Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.07172","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5a2607d7f930876d460b7b987c7887fc2f5e57a9bf6e72c4dfde8f7a593015a8","sha256:17da48594988452bf03398b7eb896dcafaaa428bb0171b7486333a9f5d8124af"],"state_sha256":"60524add6a60215d4adb00d8b3337c7aeefab3203a7824fda17d0794cd875502"}
