摘要:

据我们所知,我们首次引入了一种严格的方法,使多智能体网络能够自配置其通信拓扑,以在多智能体规划过程中平衡可扩展性与最优性之间的权衡。我们的动机来自无处不在的协作自主的未来,届时大量分布式智能体将通过智能体间通信进行协调,以执行交通监控、事件检测和环境探索等复杂任务。但是,此类大规模网络中信息的爆炸式增长目前限制了它们的部署,因为现有近最优协调算法的计算和通信需求会导致不切实际的决策时间。为了克服这一挑战,我们提出了交替协调与网络设计算法(Anaconda),这是一种可扩展的算法,同时也享有近最优性保证。在智能体带宽约束下,Anaconda 使智能体能够优化其局部通信邻域,从而使网络的动作协调近似性能最大化。与现有最先进技术相比,Anaconda 是一种随时自配置算法,能够量化其对于任何类型网络(从完全断开到完全集中式)的次优性保证,并且对于稀疏网络,其决策速度提高一个数量级。为了开发该算法,我们量化了由于去中心化(即由于通信最小化的分布式协调)而产生的次优性代价。我们还采用了受多臂老虎机和受基数约束的子模最大化文献启发的工具。我们在区域监控的模拟场景中演示了 Anaconda,并将其与一种最先进的算法进行了比较。

英文摘要:

We introduce the first, to our knowledge, rigorous approach that enables multi-agent networks to self-configure their communication topology to balance the trade-off between scalability and optimality during multi-agent planning. We are motivated by the future of ubiquitous collaborative autonomy where numerous distributed agents will be coordinating via agent-to-agent communication to execute complex tasks such as traffic monitoring, event detection, and environmental exploration. But the explosion of information in such large-scale networks currently curtails their deployment due to impractical decision times induced by the computational and communication requirements of the existing near-optimal coordination algorithms. To overcome this challenge, we present the AlterNAting COordination and Network-Design Algorithm (Anaconda), a scalable algorithm that also enjoys near-optimality guarantees. Subject to the agents' bandwidth constraints, Anaconda enables the agents to optimize their local communication neighborhoods such that the action-coordination approximation performance of the network is maximized. Compared to the state of the art, Anaconda is an anytime self-configurable algorithm that quantifies its suboptimality guarantee for any type of network, from fully disconnected to fully centralized, and that, for sparse networks, is one order faster in terms of decision speed. To develop the algorithm, we quantify the suboptimality cost due to decentralization, i.e., due to communication-minimal distributed coordination. We also employ tools inspired by the literature on multi-armed bandits and submodular maximization subject to cardinality constraints. We demonstrate Anaconda in simulated scenarios of area monitoring and compare it with a state-of-the-art algorithm.
