提出了一个求解具有有界Hessian的无约束凸优化问题的连续时间二阶优化算法。我们表明,这种替代算法具有可比的收敛速度的连续时间牛顿-拉夫逊方法,但在结构上,它是服从一个更有效的分布式实现。我们提出了一个分布式实现我们提出的优化算法,并通过李雅普诺夫分析证明其收敛性。一个数值例子证明了我们的结果。
We propose a continuous-time second-order optimization algorithm for solving unconstrained convex optimization problems with bounded Hessian. We show that this alternative algorithm has a comparable convergence rate to that of the continuous-time Newton–Raphson method, however structurally, it is amenable to a more efficient distributed implementation. We present a distributed implementation of our proposed optimization algorithm and prove its convergence via Lyapunov analysis. A numerical example demonstrates our results.
