An extensive experimental evaluation shows that Z3-Noodler is a fully-fledged solver that can compete with state-of-the-art solvers, surpassing them by far on many benchmarks. Moreover, it is often complementary to other solvers, making it a suitable choice as a candidate to a solver portfolio.","authors_text":"David Chocholat\\'y, Juraj S\\'i\\v{c}, Luk\\'a\\v{s} Hol\\'ik, Ond\\v{r}ej Leng\\'al, Vojt\\v{e}ch Havlena, Yu-Fang Chen","cross_cats":["cs.FL"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LO","submitted_at":"2023-10-12T13:43:52Z","title":"Z3-Noodler: An Automata-based String Solver (Technical Report)"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2310.08327","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":"sha256:89c571c480058f457dc74bad1606fbeac07f53737cce978b0edae2e45a65b9a2","target":"record","created_at":"2026-07-05T07:01:47Z","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":"a66e1cc5466fe204f32ba1084bb43045f5b9c363f123f18eb77095500528a3b6","cross_cats_sorted":["cs.FL"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LO","submitted_at":"2023-10-12T13:43:52Z","title_canon_sha256":"2fe04f83a09325703b66eaac1d1a9bed89ff8c31d9664db4e59327db88dfbaeb"},"schema_version":"1.0","source":{"id":"2310.08327","kind":"arxiv","version":2}},"canonical_sha256":"8c791c6bb0d31bde26379a3629b06d07c361536b3dd10a798f0e077034cba505","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8c791c6bb0d31bde26379a3629b06d07c361536b3dd10a798f0e077034cba505","first_computed_at":"2026-07-05T07:01:47.757038Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:01:47.757038Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"74RznypxH//WbZjAKWYjXpdDMxRWk1B/p+puK0m2M5Rv8iVcWJCgar+/0LxDA0TzWM95GsqlFKFpYwSOBK4BCA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:01:47.757848Z","signed_message":"canonical_sha256_bytes"},"source_id":"2310.08327","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:89c571c480058f457dc74bad1606fbeac07f53737cce978b0edae2e45a65b9a2","sha256:fed5b06a6bd057a1a31cf2339dc71a59e4f83fa75e361ba8878a48277c3b16d9"],"state_sha256":"600024b914bfdf212a97f71c8d0d2d586ad5a65448e2084568750bf3b5226a68"}
