Using a well-established model of opinion dynamics, we formulate the problem as a zero-sum game with its players being the two camps. We derive optimal investment strategies for both camps, and show that a random investment strategy is optimal when the underlying network follows a popular class of weight distributions. We study a broad framework, where we consider various well-motivated settings of the proble","authors_text":"Eitan Altman, Swapnil Dhamal, Tijani Chahed, Walid Ben-Ameur","cross_cats":["physics.soc-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2017-06-28T14:02:41Z","title":"Optimal Investment Strategies for Competing Camps in a Social Network: A Broad Framework"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.09297","kind":"arxiv","version":5},"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":"sha256:88a4a4b9bd73d57bf761eea84f1559fb193a32a349cae09471a07da9eef75248","target":"record","created_at":"2026-05-18T00:08:27Z","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":"97b489ecb523b5459e39c4f1158b5b2a6deb67dfa2cfff03a789b769712d0dc1","cross_cats_sorted":["physics.soc-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2017-06-28T14:02:41Z","title_canon_sha256":"f7f08095e0bb538170f659e316a0c9d5f1cdd7a28bea9c7327a3f945b3b7a08d"},"schema_version":"1.0","source":{"id":"1706.09297","kind":"arxiv","version":5}},"canonical_sha256":"42bb444cba0138e9db596f137e21434149a4974d62d20d37daa4eeb74ccfc3a6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"42bb444cba0138e9db596f137e21434149a4974d62d20d37daa4eeb74ccfc3a6","first_computed_at":"2026-05-18T00:08:27.274805Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:08:27.274805Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2/Z0T7X73X/BaVXK+xKWKPZy52UHNSe5cf0bN8eeqe3WDhEi51f63zDieqf7lDmLPUltFldxewJS5kIw/7sSCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:08:27.275238Z","signed_message":"canonical_sha256_bytes"},"source_id":"1706.09297","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:88a4a4b9bd73d57bf761eea84f1559fb193a32a349cae09471a07da9eef75248","sha256:aeb6bcf16ba6d5a286b9cdc83d9c99105310dadbca3a978629a10ae349b41862"],"state_sha256":"64fc34942bcdf858e660749c7aca8934fb29f90e82e38e8144ab8b35bfda48a6"}
