简介
In decentralized optimization environments, each agent i in a network of n nodes has its own private function f i , and nodes communicate with their neighbors to cooperatively minimize the aggregate objective . In this setting, synchronizing the nodes’ updates incurs significant communication overhead and computational costs, so much of the recent literature has focused on the analysis and design of asynchronous optimization algorithms, where agents activate and communicate at arbitrary times without needing a global synchronization enforcer. However, most works assume that when a node activates, it selects the neighbor to contact based on a fixed probability (e.g., uniformly at random), a choice that ignores the optimization landscape at the moment of activation. Instead, in this work we introduce an optimization-aware selection rule that chooses the neighbor providing the highest dual cost …
