In order to reduce communication costs, the positions of the servers can be adapted by a limited distance m_s per round for each server. The costs are measured similar to the classical Page Migration Problem, i.e., answering a request induces costs proportional to the distance to the nearest server, and moving a server induces costs proportional to the distance multiplied with a weight D.\n  We show that, in ou","authors_text":"Bj\\\"orn Feldkord, Friedhelm Meyer auf der Heide, Manuel Malatyali, Till Knollmann","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2019-07-23T12:07:33Z","title":"Managing Multiple Mobile Resources"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.09834","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:de85949e07b2576750a48a8f67f646be6e5569d8a2b0f57be6e6c942b99c1a14","target":"record","created_at":"2026-05-17T23:39:49Z","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":"ff04dcf759bf8e71d68c7a9f6cb964fa698fb6f097cd4e69338781ea7b557e58","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2019-07-23T12:07:33Z","title_canon_sha256":"d8c16818e49649862e0e1542e023b2d58d2ef113f2917ef07c422f7ee64709aa"},"schema_version":"1.0","source":{"id":"1907.09834","kind":"arxiv","version":1}},"canonical_sha256":"ab49134397c53365ba61ef3a021fc2a6878ca63f3dec3b7c037f92aa4fd0dede","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ab49134397c53365ba61ef3a021fc2a6878ca63f3dec3b7c037f92aa4fd0dede","first_computed_at":"2026-05-17T23:39:49.924456Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:39:49.924456Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/hcf3zALCnGMmGrigSklpeIaGPey7MpsYFX/oHl3xyDw/YP+lJwFgfsXs8qQI5wCQm6LB2vSFSHha4t76E4NAg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:39:49.925044Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.09834","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:de85949e07b2576750a48a8f67f646be6e5569d8a2b0f57be6e6c942b99c1a14","sha256:f6d7bfa4f0d8f12c9156376da47a3633d4080c7a16aadc065b2aec0f067c9a0f"],"state_sha256":"c703a5664ed6c046da6e547fad4f6df2a5efaebf7cb25e65651de70446bf0c99"}
