Organizations often pool dispersed information into one ranking and then allow many agents to act on that shared view. In a discovery problem, this can improve beliefs while reducing coverage.

The paper introduces a decentralized learning framework for finding socially optimal equilibria in finite normal-form games played over dynamic communication networks. Agents only observe their own payoffs, lack prior knowledge of the game, and communicate with time-varying neighbors using low-bandwidth, time-stamped tables instead of raw actions or payoff data. The proposed dynamics combine randomized semantic signals, table fusion, and temporal majority reconstruction to achieve finite-time logarithmic regret guarantees for optimal equilibrium selection under utilitarian and proportional-fair social welfare objectives, as demonstrated by simulations.

The paper introduces a decentralized decision-making framework for teams operating under partial observability and unknown system dynamics. By leveraging low-rank latent dynamics and delayed shared information, each team member learns an approximate Markov decision process using only local private data and delayed common updates. The resulting algorithm achieves near‑optimal team performance without requiring a centralized coordinator or training, and the authors provide finite‑sample guarantees and a sample‑complexity bound.
