(Partial weighted) MaxSMT --or equivalently OMT with Pseudo-Boolean objective functions, OMT+PB-- is a very-relevant strict subcase of OMT. We classify existing approaches for MaxSMT or OMT+PB in two groups: MaxSAT-based approaches exploit the efficiency of state-of-the-art MAXSAT solvers, but they are specific-purpose and not always applicable; OMT-based approaches are general-purpose, but they suffer from intrinsic inefficiencies on MaxSMT/OMT+PB problems.\n  We identify a","authors_text":"Patrick Trentin, Roberto Sebastiani","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2017-02-08T11:52:15Z","title":"On Optimization Modulo Theories, MaxSMT and Sorting Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.02385","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":"sha256:769cdfb06faaf185f0ce69d94fe5eba277af1a543b1d9798e9b6054719544beb","target":"record","created_at":"2026-05-18T00:51:06Z","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":"5e44fed94b42d9c39c23d74b69690ff5376aa4b8cfb3fdb34626b63b6722b26e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2017-02-08T11:52:15Z","title_canon_sha256":"4959e5959e18ef1d61e59651f4417e41fba4ae73218f18d796e9b13ea92a881a"},"schema_version":"1.0","source":{"id":"1702.02385","kind":"arxiv","version":1}},"canonical_sha256":"afa557d36a7c2a32affb65942cb919ecca5bc493b1f58b69bc9567ec02016d05","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"afa557d36a7c2a32affb65942cb919ecca5bc493b1f58b69bc9567ec02016d05","first_computed_at":"2026-05-18T00:51:06.052921Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:51:06.052921Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wm9agtdlJV9kB2t7myzrBWyStdSKX8Fm6rvtuJ8qs6v+Y0ktW3zn5Pu3J3NDZA+QaO/32tVhDFyZYRdJiVF+AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:51:06.053331Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.02385","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:769cdfb06faaf185f0ce69d94fe5eba277af1a543b1d9798e9b6054719544beb","sha256:cbb4f34848621bce346d641a110bcdfbfac2d6987fc3e7e20b5d832f5918c32f"],"state_sha256":"dedea10add5af67f02fa02d05a28633d0f6fcee9c5755ec4155ac97dd5742933"}
