We propose, in particular, an algorithm which entails, at each step, projecting onto a suitably chosen half-space, and prove that the sequences it generates converge to the unique solution of the VIP. We also present an application of our result to a hierarchical optimization problem.","authors_text":"Andrzej Cegielski, Aviv Gibali, Rafa{\\l} Zalas, Simeon Reich","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2013-04-02T16:54:19Z","title":"An algorithm for solving the variational inequality problem over the fixed point set of a quasi-nonexpansive operator in Euclidean space"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1304.0690","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":"sha256:93cd3e568890921899d4702aaba1a9cc72d3ed5c820980698d060bf98df674dc","target":"record","created_at":"2026-05-18T03:29:14Z","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":"9e0d19dfcfe82822589d12a2104319a45059f2ecad9d2972e9425109251a1a01","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2013-04-02T16:54:19Z","title_canon_sha256":"600d86a6a003e1bacb8652a2220356eeae065f3ff42eecbbd720b1309db8eec9"},"schema_version":"1.0","source":{"id":"1304.0690","kind":"arxiv","version":1}},"canonical_sha256":"8fcc1d4e6e360a9dde372722fd4bf802e4d5a6e7dc6e8b05bf486ef9437765cb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8fcc1d4e6e360a9dde372722fd4bf802e4d5a6e7dc6e8b05bf486ef9437765cb","first_computed_at":"2026-05-18T03:29:14.613218Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:29:14.613218Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4ku8OfqxY1NBs4tCdW2ZpcVYPphF4UfqUe9Cgc8sHY0duCkXw0VLiXM2V+hBAM32pwsVjtp2ACjEbXfM2gwtDw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:29:14.613839Z","signed_message":"canonical_sha256_bytes"},"source_id":"1304.0690","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:93cd3e568890921899d4702aaba1a9cc72d3ed5c820980698d060bf98df674dc","sha256:a3d2858fe3569ce4e79802821708da7acc670c5c50f681387df8b6d0ec211c09"],"state_sha256":"3e0ad4903273b52ea04877490059919b0eaa159b90df1e64e3fd864fd9bd1031"}
