Chaotic variation has been used to great advantage on music and dance, but the challenges here are quite different, beginning with the representation. We present a formalized system for transcribing rock climbing problems, then describe a variation generator that is designed to support human route-setters in designing new and interesting climbing problems. This variation generator, termed Strange Beta, combines chaos and machine learning, using the former to introduce novelty ","authors_text":"Caleb Phillips, Elizabeth Bradley, Lee Becker","cross_cats":["cs.HC","stat.AP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2011-10-03T22:23:46Z","title":"Strange Beta: An Assistance System for Indoor Rock Climbing Route Setting Using Chaotic Variations and Machine Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1110.0532","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:b64c0cb21d60cdee6e75d382266c93a2ec51e8c42ed98dfcfa2db877d6bcfbc1","target":"record","created_at":"2026-05-18T02:51:23Z","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":"1d1671f41a11f5562cf65104005f45af2964c735df3c1992984a2acf8ce9907e","cross_cats_sorted":["cs.HC","stat.AP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2011-10-03T22:23:46Z","title_canon_sha256":"2f1980ed5f1416496c7ed5f5cf3e9be2337d65eeb2f4099c8d7859f46751a2f7"},"schema_version":"1.0","source":{"id":"1110.0532","kind":"arxiv","version":1}},"canonical_sha256":"dcf3194a8d81705934148af63cb92699935870e368edbd3240b1f3a932a94b30","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dcf3194a8d81705934148af63cb92699935870e368edbd3240b1f3a932a94b30","first_computed_at":"2026-05-18T02:51:23.704816Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:51:23.704816Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9hHoRlxGe4hwbshmoa/ojQTe6hbqqM0N09r8eLlJALL4j6BPVbdC1upydw4fIGiHdQ3C3ioDoyt/9pjCU+MZBw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:51:23.705373Z","signed_message":"canonical_sha256_bytes"},"source_id":"1110.0532","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b64c0cb21d60cdee6e75d382266c93a2ec51e8c42ed98dfcfa2db877d6bcfbc1","sha256:a5b9cf89b93d2f9eb53638dcea3825df00d47c95fd9caa8ce577939336b0445e"],"state_sha256":"33be491d2e0b94dc29fffcba4db26291e37489a5a572e3401b301b48c6cf828d"}
