带约束的分布式凸优化的多尺度方法

A Multi-Scale Method for Distributed Convex Optimization with Constraints

Wei Ni, Xiaoli Wang

摘要:

针对约束凸优化问题,提出了一种多尺度分布式算法,该算法利用多智能体的马尔可夫切换网络动态特性和智能体间的噪声通信来设计连续时间分布式算法.不同于以往大多数工作,主要是把重点放在处理固定的网络拓扑结构,本文解决了具有挑战性的问题,调查随机网络和代理间的通信噪声的联合影响的分布式优化动力学,这还没有系统地研究在过去的文献。此外,在约束优化以前的工作形成鲜明对比,我们离开使用的投影梯度流,这是非光滑的,难以分析,而是,我们设计了一个光滑的优化动力学,从而导致更容易的收敛性分析和更有效的数值模拟。此外,本文提出的多尺度方法推广了以前已知的分布式凸优化算法从固定的网络拓扑的切换情况下,本文得到的随机平均是现有的确定性平均的推广。

英文摘要:

This paper proposes a multi-scale method to design a continuous-time distributed algorithm for constrained convex optimization problems by using multi-agents with Markov switched network dynamics and noisy inter-agent communications. Unlike most previous work which mainly puts emphasis on dealing with fixed network topology, this paper tackles the challenging problem of investigating the joint effects of stochastic networks and the inter-agent communication noises on the distributed optimization dynamics, which has not been systemically studied in the past literature. Also, in sharp contrast to previous work in constrained optimization, we depart from the use of projected gradient flow which is non-smooth and hard to analyze; instead, we design a smooth optimization dynamics which leads to easier convergence analysis and more efficient numerical simulations. Moreover, the multi-scale method presented in this paper generalizes previously known distributed convex optimization algorithms from the fixed network topology to the switching case and the stochastic averaging obtained in this paper is a generalization of the existing deterministic averaging.
