It is a reversible preprocessing step that rearranges an $n$-letter string into runs of identical characters (by exploiting context regularities), resulting in highly compressible strings, and is the basis of the \\texttt{bzip} compression program. Alas, the decoding process of BWT is inherently sequential and requires $\\Omega(n)$ time even to retrieve a \\emph{single} character.\n  We study the succinct data structure problem of locally decoding short substrings of a given text unde","authors_text":"Omri Weinstein, Sandip Sinha","cross_cats":["cs.CC","cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2018-08-12T18:16:59Z","title":"Local Decodability of the Burrows-Wheeler Transform"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.03978","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:be1becebf9a446cd6401bf48be6a9b40b39be723edce06d40d0cf3b9b4820176","target":"record","created_at":"2026-05-17T23:59:01Z","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":"d3fdb445404610bb89fdfd9400e3891f09070a539f3f6aa06b523d0a04ea3efc","cross_cats_sorted":["cs.CC","cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2018-08-12T18:16:59Z","title_canon_sha256":"187d6006a106801ed5f62b84db1e0bfbb02aee64a3cfb0428c689a15985a49ca"},"schema_version":"1.0","source":{"id":"1808.03978","kind":"arxiv","version":2}},"canonical_sha256":"bc46f6db68cdb093d6986f500489b1ce67238ee2d21990306f36f0945a0e0c44","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bc46f6db68cdb093d6986f500489b1ce67238ee2d21990306f36f0945a0e0c44","first_computed_at":"2026-05-17T23:59:01.529713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:01.529713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bmHWxkH4Bg3JZjPK2WztsIvjr5lHme18LepGkCAgeFerCdTzIZExpiHPn7/YUfOZx2Y993EANCjhvWolUP+6AA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:01.530276Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.03978","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:be1becebf9a446cd6401bf48be6a9b40b39be723edce06d40d0cf3b9b4820176","sha256:a4d8887057fb451dfb8b904989bda34c398ea5dcc2c24cd897a5e51765e9c2dd"],"state_sha256":"c6a6f8b71642e6060bc31efaed10e481b1ce6ffe72019e1a20f6d4f8bd8b4495"}
