In essence, an FQL test specification amounts to a set of regular languages, each of which has to be matched by at least one test execution. To describe such sets of regular languages, the FQL semantics uses an automata-theoretic concept known as rational sets of regular languages (RSRLs). RSRLs are automata whose alphabet consists of regular expressions. Thus, the language accepted by the automaton is a set of regular expres","authors_text":"Andreas Holzer, Christian Schallhart, Helmut Veith, Michael Tautschnig","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.FL","submitted_at":"2013-05-26T22:05:23Z","title":"On the Structure and Complexity of Rational Sets of Regular Languages"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.6074","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:fa6df39851b3cf01ec1cc4b6d7632e88134509bf4e2998546e96085b8c4bc116","target":"record","created_at":"2026-05-18T03:24:53Z","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":"77a2315c75028f83d74b01ade5d6c334d2085025eaf0810c57abda3ea39488a5","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.FL","submitted_at":"2013-05-26T22:05:23Z","title_canon_sha256":"c6bb3fdaf54ffc258cb540e2a69b8224e16df5f82bd5cd916f64d6be5928459d"},"schema_version":"1.0","source":{"id":"1305.6074","kind":"arxiv","version":1}},"canonical_sha256":"06e625c98343493cc7bc3ffabbe6e1dcf60b3c83a4257bdc13bd0947669f15d8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"06e625c98343493cc7bc3ffabbe6e1dcf60b3c83a4257bdc13bd0947669f15d8","first_computed_at":"2026-05-18T03:24:53.010061Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:24:53.010061Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"661KljH4FNvf9hywPnzqqPMTw9rfnVX0aAOIrxS2c0Q+5/+UCU92IbMaRF3yC23vc7SWajXT9jYW38eDv7SsDg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:24:53.010813Z","signed_message":"canonical_sha256_bytes"},"source_id":"1305.6074","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fa6df39851b3cf01ec1cc4b6d7632e88134509bf4e2998546e96085b8c4bc116","sha256:a578f8edb9b2cff3f1794555150568665cf677bff19e11cec9bc91423431f6be"],"state_sha256":"fb7717aeac4f8a472b0b0cdcf7cae05b151e8d219499bf8310e26e9352a0bb9e"}
