The machine requires a setup taking $s$ time units whenever it switches from processing jobs of one type to jobs of a different type. We consider the problem as an online problem where each job is only known to the scheduler as soon as it arrives and where the processing time of a job only becomes known upon its completion (non-clairvoyance).\n  We are interested in the potential of simple \"greedy-lik","authors_text":"Alexander M\\\"acker, Friedhelm Meyer auf der Heide, Manuel Malatyali, S\\\"oren Riechers","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2017-09-18T12:37:40Z","title":"Non-Clairvoyant Scheduling to Minimize Max Flow Time on a Machine with Setup Times"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.05896","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:ee3f12622fe6f14513ccf4ce630659179331df75c87b427016e9e24b6b8ee2c1","target":"record","created_at":"2026-05-18T00:34:58Z","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":"0f85023ae3749b90002da1b85c59eb51df53e011b0c02ddfe3afd0fc915d979c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2017-09-18T12:37:40Z","title_canon_sha256":"81c705636238c7244a6aa855fbc6fedb2ca2fd90cb909f5e0abe3d91889a76fe"},"schema_version":"1.0","source":{"id":"1709.05896","kind":"arxiv","version":1}},"canonical_sha256":"9fc0dc610cc0b9eb1b5c4062b29c57c283d613e3bbc2446483743027a896913c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9fc0dc610cc0b9eb1b5c4062b29c57c283d613e3bbc2446483743027a896913c","first_computed_at":"2026-05-18T00:34:58.956806Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:58.956806Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dS5Y0XXJ/7c3IcLLppr9C8Ep02UasYMlyR1eDIqPfmwUTJ3kHr1C9yo/MOdgI+nHXaao92lXUzrZq5kGuAj1Bg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:58.957548Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.05896","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ee3f12622fe6f14513ccf4ce630659179331df75c87b427016e9e24b6b8ee2c1","sha256:f26cb8a7ae37ca8896c4dc0051ec4c3582e961ef7490fe7b19e27e1f36419f32"],"state_sha256":"5f091088852a691ebdde776699081c4adaab1451fde4d966ba9944d668f41c87"}
