Indeed, the growing prevalence of matching-based markets, many of which online in nature, has motivated much research in economics, operations research, computer science, and their intersection. This brief survey is meant as an introduction to the area of online matching, with an emphasis on recent trends, both technical and conceptual.","authors_text":"David Wajc, Zhihao Gavin Tang, Zhiyi Huang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DS","submitted_at":"2024-07-07T14:07:54Z","title":"Online Matching: A Brief Survey"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2407.05381","kind":"arxiv","version":1},"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:ed0c421070bc0fb6fca9b2ba7849e1a66ef84154a286c65127e00faef6046202","target":"record","created_at":"2026-07-05T08:41:12Z","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":"7ff5038e476b9add321db861788ffbad8732756fee3d38fc6697e3d2067739df","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DS","submitted_at":"2024-07-07T14:07:54Z","title_canon_sha256":"2a1e0578d7e8c46e3ba3881c46ac6f04031347d6ec1470c7d7cdec6274c27b56"},"schema_version":"1.0","source":{"id":"2407.05381","kind":"arxiv","version":1}},"canonical_sha256":"9a75204d55c7d23954df52db02ec66caf5508c3d69599b8c228f79da29a50d7b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a75204d55c7d23954df52db02ec66caf5508c3d69599b8c228f79da29a50d7b","first_computed_at":"2026-07-05T08:41:12.245122Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:41:12.245122Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SW2a+VeKNyDB8ERnf9v7dW5scKnf/zSFXnWsQvHqMeQ0+3VGVa/Wk7QbhFARGWXoyzopERC0xfXjeud3Sz4UBA==","signature_status":"signed_v1","signed_at":"2026-07-05T08:41:12.245568Z","signed_message":"canonical_sha256_bytes"},"source_id":"2407.05381","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ed0c421070bc0fb6fca9b2ba7849e1a66ef84154a286c65127e00faef6046202","sha256:ed603ac99f8895aab4a0386c067e990afcfbd16b2511ec664a98e95517eec26c"],"state_sha256":"371733eb464bb2769be449d2c960a0ba5bddd8f2d8f3b1e4efd90c43736aa239"}
