Both the terrain and the obstacles are modeled as arbitrary polygons. We consider two scenarios: the unlimited vision, when the robot situated at a point p of the terrain explores (sees) all points q of the terrain for which the segment pq belongs to the terrain, and the limited vision, when we require additionally that the distance between p and q be at most 1. All points of the terrain (except obstacles) have to be explored and the performance of an exploration algorithm is measured by","authors_text":"Andrzej Pelc, Arnaud Labourel (LaBRI), David Ilcinkas (LaBRI, INRIA Bordeaux - Sud-Ouest), Jurek Czyzowicz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2010-01-05T07:29:11Z","title":"Optimal Exploration of Terrains with Obstacles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1001.0639","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":"sha256:002e2ee461d4904ae7f049158d4f61149526abcb19feef68bb8f88d7a5384f9d","target":"record","created_at":"2026-05-18T02:10:05Z","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":"fd6db917faf714b05e61d66a2a2a6b02363a80b475897bb43e6f3018dc2302b2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2010-01-05T07:29:11Z","title_canon_sha256":"6500954366cd60fd4344706cc12cc722970d95ad013713c7b82f49239a420da2"},"schema_version":"1.0","source":{"id":"1001.0639","kind":"arxiv","version":1}},"canonical_sha256":"2a0586b9f2a81d9e576ef05019c19e890af0b730a2885fb569a75e58c1761f19","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2a0586b9f2a81d9e576ef05019c19e890af0b730a2885fb569a75e58c1761f19","first_computed_at":"2026-05-18T02:10:05.090859Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:10:05.090859Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VUFodAw6XSCmGhqdIzWrKyZgbdfYCZ3fOTvGs+4ck1r+Vm8+bvGtNKUAkH1xvJQX24FAPPqdF72fIpak1vR+DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:10:05.091574Z","signed_message":"canonical_sha256_bytes"},"source_id":"1001.0639","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:002e2ee461d4904ae7f049158d4f61149526abcb19feef68bb8f88d7a5384f9d","sha256:de2a616a78f7f0f1b3ca07fe2dca00ec7f38d9711e994ab6feaa3c1cec8bd5d7"],"state_sha256":"9e783c8d4f5dcf3b0a9aa2f7aff99ac7e8ff125160c5b91c2b330c8bb5c84497"}
