However, they often struggle with generalization to larger problem instances or different VRP variants. This paper revisits light decoder-based approaches, analyzing the implications of their reliance on static embeddings and the inherent challenges that arise. Specifically, we demonstrate that in the light decoder paradigm, the encoder is implicitly tasked with capturing information for all potential decision sce","authors_text":"Jianan Zhou, Yixin Xu, Zhiguang Cao, Ziwei Huang","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2025-03-02T06:13:00Z","title":"Rethinking Light Decoder-based Solvers for Vehicle Routing Problems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.00753","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":"sha256:9aa13e03955b1aee9ef39183677cca8d6109975dc49ab7387e33122b6b7dbf1a","target":"record","created_at":"2026-07-05T10:22:28Z","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":"35e55f7f98e89202816e263aed72eb128e2af255f15afe3effa28f4fea7c7483","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2025-03-02T06:13:00Z","title_canon_sha256":"2044cc2f0fb33e6a61b94a8acb627b63f6ae2bd724952b11e90e41cbe7a6854d"},"schema_version":"1.0","source":{"id":"2503.00753","kind":"arxiv","version":1}},"canonical_sha256":"6faa3ce6145de3ef445d05aa043036e3de28f529a4150b7ac8e2eb1ac0552636","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6faa3ce6145de3ef445d05aa043036e3de28f529a4150b7ac8e2eb1ac0552636","first_computed_at":"2026-07-05T10:22:28.689336Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:22:28.689336Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+RC3TkbemNFm1LYhw9pGaQcfN5MWHbNG//rw3Mqlz53dWX9th22Frm2NmZEQ7fedvVcKT6Wa1Dqy1/kjvc5LBA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:22:28.689844Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.00753","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9aa13e03955b1aee9ef39183677cca8d6109975dc49ab7387e33122b6b7dbf1a","sha256:b4fb18964bd66e9720ea96232725edc90b45c325335cd297921136a197550d5d"],"state_sha256":"c0879f2830dc10890113c0ce1c505f705d9195edfff9482d7bc1147df276d2b7"}
