This often leads to structures of interest in these models composed of dense packs of entities. Fast Multipole Methods are a family of methods developed to help with the calculation of a number of computable models such as described above. We propose a method that builds upon FMM to detect and model the dense structures of these systems.","authors_text":"Antoine Dutot (LITIS), Pierrick Tranouez (LITIS)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2009-10-06T14:19:56Z","title":"Building upon Fast Multipole Methods to Detect and Model Organizations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.1014","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:f5af6d202e52840027bb30755e2837c0646f3e09caf6dc2bab8071f3d5ce2bb6","target":"record","created_at":"2026-07-04T15:53:56Z","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":"64c71667ebc80d59f9218a1c66d9056f9fefcc86b6a78e75f643b134dc241f2a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2009-10-06T14:19:56Z","title_canon_sha256":"740d2f6b07c871f56bde6d0c7556d71d3045a3ddef7054bcd75285e1bd992387"},"schema_version":"1.0","source":{"id":"0910.1014","kind":"arxiv","version":2}},"canonical_sha256":"47cba23cd9ee668d84e7f91d8719bf08059b886b12c59942896232696b91fd35","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"47cba23cd9ee668d84e7f91d8719bf08059b886b12c59942896232696b91fd35","first_computed_at":"2026-07-04T15:53:56.847254Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:53:56.847254Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WBjagAuzlbVUm3MBrtuQR1acEifYBWS3ujQXXOwy1vNLcLrDQTYMQX9RfCP96Xx3+H+Sh7EmMdLjoGjL6t0BCQ==","signature_status":"signed_v1","signed_at":"2026-07-04T15:53:56.847632Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.1014","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f5af6d202e52840027bb30755e2837c0646f3e09caf6dc2bab8071f3d5ce2bb6","sha256:c0ff407f9abe8c152432e421e2c90dedc59a1ac259b586088817b01cf5de6619"],"state_sha256":"45a5dac857f28fe51fe188ff54f5a66535b82ef93910c3b8ba55b647e3269504"}
