In this technical report, we extend three dynamic approaches - Naive-dynamic (ND), Delta-screening (DS), and Dynamic Frontier (DF) - to our multicore implementation of the Leiden algorithm, known for its high-quality community detection. Our experiments, conducted on a server with a 64-core AMD EPYC-7742 processor, show that ND, DS, and DF Leiden achieve average speedups of 1.37x, 1.47x, and 1.98x on large graphs with random batch updates, compared to the Static Leiden algorithm - while scaling at a","authors_text":"Subhajit Sahu","cross_cats":["cs.SI"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.DC","submitted_at":"2024-05-19T20:10:55Z","title":"A Starting Point for Dynamic Community Detection with Leiden Algorithm"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.11658","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":"sha256:2ee4a0d53e141896aa991ad45e4c8dab3c92eccd7bc0c67edec0a6e5f6fe9462","target":"record","created_at":"2026-07-05T09:54:26Z","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":"be582a1121db291f27698bb6d6252e6be686f976c17d976ba65dcf21c2cbd741","cross_cats_sorted":["cs.SI"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.DC","submitted_at":"2024-05-19T20:10:55Z","title_canon_sha256":"dafa27c4b25e42cddace7a0af2b8c0201500c491ed0ce3d3b76a5d0ac34098db"},"schema_version":"1.0","source":{"id":"2405.11658","kind":"arxiv","version":4}},"canonical_sha256":"3c629607a2a0e4c9e292d8ce5a9cbc2562306191f74e89fbabfbd89e43befdeb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3c629607a2a0e4c9e292d8ce5a9cbc2562306191f74e89fbabfbd89e43befdeb","first_computed_at":"2026-07-05T09:54:26.747387Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:54:26.747387Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WGkcW9JpS1D0J1sGLwfbtltvyxQ7pb9wPvK/ow4um3F6c8PFzUbL11Xm4NIbGq5qmxyv1GkNCDQSUJ6HgoMwDg==","signature_status":"signed_v1","signed_at":"2026-07-05T09:54:26.747904Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.11658","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2ee4a0d53e141896aa991ad45e4c8dab3c92eccd7bc0c67edec0a6e5f6fe9462","sha256:efe0b5ab5c9f846044f01514d6b670bd15c9575fe5843fa5dcad081df3b3b6df"],"state_sha256":"4412acedf902bee48b92029242aae33cc2feb4814e6bf85265b11c64c06c8282"}
