In several scenarios, having a high betweenness can have a positive impact on the node itself. Hence, in this paper we consider the problem of determining how much a vertex can increase its centrality by creating a limited amount of new edges incident to it. In particular, we study the problem of maximizing the betweenness score of a given node -- Maximum Betweenness Improvement (MBI) -- and that of maximizing the ranking of a given node -- Maximum Ranking Im","authors_text":"Elisabetta Bergamini, Gianlorenzo D'Angelo, Henning Meyerhenke, Lorenzo Severini, Pierluigi Crescenzi, Yllka Velaj","cross_cats":["cs.SI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2017-02-17T10:00:58Z","title":"Improving the betweenness centrality of a node by adding links"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.05284","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":"sha256:3a1c033bfe61660ff0330c25ba4e4698c439a4f7464f1b349b5b03fe787c1bd9","target":"record","created_at":"2026-05-18T00:09:10Z","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":"0d69804baa0ea0c2646a1a59c32eb568cd7494e81de1a0d00ac530900261a0b1","cross_cats_sorted":["cs.SI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2017-02-17T10:00:58Z","title_canon_sha256":"5639a577eaffb8c273dcca4887620b59225dce929347106945f1fab3d9db6bc3"},"schema_version":"1.0","source":{"id":"1702.05284","kind":"arxiv","version":2}},"canonical_sha256":"07a7e395b597494c087f858b052eb75027be906fc7fdc9e73294ae9506f4120b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"07a7e395b597494c087f858b052eb75027be906fc7fdc9e73294ae9506f4120b","first_computed_at":"2026-05-18T00:09:10.142702Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:10.142702Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bBHizy48gSqYjZ70wKG2zc95huP/V+X0LRNXoRlIIW4ZukDMc02vsAeVUdf2+XyzXqwFMFBCaIEIwqho3YE7BA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:10.143220Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.05284","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3a1c033bfe61660ff0330c25ba4e4698c439a4f7464f1b349b5b03fe787c1bd9","sha256:42de7ff59fbb8b68280bf0c35aec1e1e57cadb77f4043dafbe923044a6feecab"],"state_sha256":"4d781800746c36935d7feabe4f04b45f666070a15c691871c98b77098d0a42d1"}
