This problem is notoriously difficult due to the interaction of two challenging vehicle routing attributes, \"pickups and deliveries\" and \"split deliveries\". This possibly leads to optimal solutions of a size that grows exponentially with the instance size, containing multiple visits per customer pair, even in the same route. To solve this problem, we propose an iterated lo","authors_text":"Luiz Satoru Ochi, Marcone Jamilson Freitas Souza, Matheus Nohra Haddad, Rafael Martinelli, Richard Hartl, Simone Martins, Thibaut Vidal","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2018-02-18T02:09:20Z","title":"Large Neighborhood-Based Metaheuristic and Branch-and-Price for the Pickup and Delivery Problem with Split Loads"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.06318","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":"sha256:254d62be3830c3618b4035a9b0dedbce1052458d5a1dabaf6e5aa56927c56070","target":"record","created_at":"2026-05-18T00:23:03Z","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":"ff02f4baf8d56f21801fa260711dd7b39484e0713c831e6cafdeca7af739ef1c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2018-02-18T02:09:20Z","title_canon_sha256":"dd6c7c9ea64534c92bbaa4e12db62854d748a1928b5c8610f267d447f1e6ea4a"},"schema_version":"1.0","source":{"id":"1802.06318","kind":"arxiv","version":1}},"canonical_sha256":"74aebae9cfe3bed2100984c710d8f13ea20372808710d08395b6c47fe87700cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"74aebae9cfe3bed2100984c710d8f13ea20372808710d08395b6c47fe87700cc","first_computed_at":"2026-05-18T00:23:03.657742Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:23:03.657742Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"f269XujUj7oG8NLecPlFC3kXKqwnL4aeEFQZvTf7wzJnakvFpCJdFbatAaPJqz3UXrso4n8Wd3rEjZO6pQgEBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:23:03.658451Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.06318","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:254d62be3830c3618b4035a9b0dedbce1052458d5a1dabaf6e5aa56927c56070","sha256:bb21768aeac57d5d9b1d181a4c240aa76e48b8cd0bfa1ccc878db2ca9fa64ae9"],"state_sha256":"4d9b5af02e67f636a20421c74acc8b9849b721192a3745ec377f4394ae11c4fc"}
