Each puzzle is defined by a short Python program $f$, and the goal is to find an input which makes $f$ return True. The puzzles are objective in that each one is specified entirely by the source code of its verifier $f$, so evaluating $f$ is all that is needed to test a candidate solution. They do not require an answer key or input/output examples, nor do they depend on natural lang","authors_text":"Adam Tauman Kalai, Ashwin Kalyan, Oleksandr Polozov, Tal Schuster","cross_cats":["cs.AI","cs.CL","cs.PL","cs.SE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-06-10T14:37:28Z","title":"Programming Puzzles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2106.05784","kind":"arxiv","version":3},"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":"sha256:8f053dedd713d64ad7bea5a8cd50f6326c1e70f152ad88b07889ebec7eff98f7","target":"record","created_at":"2026-07-05T03:29:49Z","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":"161f58a28f6b3e18c861ecf3c40018a274d15052adf527a113297a7097aed78e","cross_cats_sorted":["cs.AI","cs.CL","cs.PL","cs.SE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2021-06-10T14:37:28Z","title_canon_sha256":"56ab495f63db2a9d42305317e523e002b3f7098f4021311219f8304e98018579"},"schema_version":"1.0","source":{"id":"2106.05784","kind":"arxiv","version":3}},"canonical_sha256":"b530758b72df7ff364a717e0c77911038809aed7c98355cc6c0cd662e229c785","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b530758b72df7ff364a717e0c77911038809aed7c98355cc6c0cd662e229c785","first_computed_at":"2026-07-05T03:29:49.924505Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:29:49.924505Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+6TgjkLO5xiMmOoGjfdwAB61aWYOwr+inPNZTY8bk9YsEUjDMLp8WR/JhaRmyB6BjX8r/phyXlPThMRlGmQBCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:29:49.924891Z","signed_message":"canonical_sha256_bytes"},"source_id":"2106.05784","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8f053dedd713d64ad7bea5a8cd50f6326c1e70f152ad88b07889ebec7eff98f7","sha256:b41644fa0d60d059c5c6ddacd5bfb893b5e490a4bb850def314b0c2c04d41c81"],"state_sha256":"861613186498ea0552e1ee00b5b274ac19219526a0a7c5e49255c45311990c87"}
