Interactions that induce alignment are essential for flocking; however, alignment alone is generally insufficient to maintain group cohesion in the presence of noise, leading traditional models to introduce artificial boundaries or explicit attractive forces. Here, we propose a model that achieves cohesive flocking through purely alignment-based interactions by introducing predictive alignment, in which agents reorient to maximize alignment with the prevailin","authors_text":"Julian Giraldo-Barreto, Viktor Holubec","cross_cats":["nlin.AO"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.soft","submitted_at":"2025-04-10T14:18:17Z","title":"Active Matter Flocking via Predictive Alignment"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.07778","kind":"arxiv","version":2},"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:ca19950c5cbaa97b4b918a720c359a69bb7c4709a085ae4ca78ecfaab2a2af78","target":"record","created_at":"2026-06-09T01:05:06Z","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":"136b1a7af09e7c7b682e5ba2e7820e6255229ca85853f7c075dd96fec405b311","cross_cats_sorted":["nlin.AO"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.soft","submitted_at":"2025-04-10T14:18:17Z","title_canon_sha256":"9d52cb33e12eb20d4c3127953b4e846461b0992cd0501deca7dbac85e3479770"},"schema_version":"1.0","source":{"id":"2504.07778","kind":"arxiv","version":2}},"canonical_sha256":"6366e4fa4013566d206a936b1fa9660f0d8f6d228077eba37aaddc79ebd31dc2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6366e4fa4013566d206a936b1fa9660f0d8f6d228077eba37aaddc79ebd31dc2","first_computed_at":"2026-06-09T01:05:06.280712Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-09T01:05:06.280712Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bhWPxg7vial8Rw5rIqnfryYEQTb2BzP1G7S7fcYQI1FcLe2jFAFZbvPAjvpqZ0CEv61qDn+PtKl7xia8EwNUAA==","signature_status":"signed_v1","signed_at":"2026-06-09T01:05:06.281164Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.07778","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ca19950c5cbaa97b4b918a720c359a69bb7c4709a085ae4ca78ecfaab2a2af78","sha256:2f9c7aaff56e87d2c705c8ebfa82816fa21415bd25c42a01933cbf355b4b7a5b"],"state_sha256":"d4bed8eb9e49f965484f310b8d1f8e88cd6fe701e754b4f95b6c2b5246fa0744"}
