The main application domain of InterHorn lies in solving interpolation problems arising in software verification. We show how a range of interpolation problems, including path, transition, nested, state/transition and well-founded interpolation can be handled directly by InterHorn. By detailing these interpolation problems and their Horn clause representations, we hope to encourage the emergence of a common back-end interpolation interface useful for diverse verification tools.","authors_text":"Andrey Rybalchenko, Ashutosh Gupta, Corneliu Popeea","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2013-03-29T12:32:56Z","title":"Generalised Interpolation by Solving Recursion-Free Horn Clauses"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.7378","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":"sha256:6228d9e120619baf7d708adc1645f8293869441e8af5b0d397d2d7ceecfa00b5","target":"record","created_at":"2026-05-18T02:32:14Z","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":"1c45c96e220408cebe6d0404e01b73423c39d4aae4303f462e40b942b055aad3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2013-03-29T12:32:56Z","title_canon_sha256":"2905d9385e0a8c915559d2084ce721c7fb2387be9d22bc7c859d6168975a4553"},"schema_version":"1.0","source":{"id":"1303.7378","kind":"arxiv","version":2}},"canonical_sha256":"4a9bd8a77239c9bf991edc007931837469601c4ad408465b3366d1186cae1e2b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4a9bd8a77239c9bf991edc007931837469601c4ad408465b3366d1186cae1e2b","first_computed_at":"2026-05-18T02:32:14.488909Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:32:14.488909Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Gl7Pg3NsM3pqNTek8zpzjGQfJ6WFgloqbiw7EEYSBsStswwAPkyiWY/gWeWfejlpYfpVGj76b7LkmNvWA85EBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:32:14.489621Z","signed_message":"canonical_sha256_bytes"},"source_id":"1303.7378","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6228d9e120619baf7d708adc1645f8293869441e8af5b0d397d2d7ceecfa00b5","sha256:205854c8a22d2e0b3bfa118758493acd585f591367de2c93c95869f8f1ccb57e"],"state_sha256":"44cfbf996f0ec142123fe9693f5545125616e200246b8c2a5ae837b9c1a02fa3"}
