Communication reduction in distributed optimization via estimation of the proximal operator
Giorgos Stathopoulos, Colin N. Jones
We introduce a reduced-communication distributed optimization scheme based on estimating the solution to a proximal minimization problem. Our proposed setup involves a group of age…
An Inertial Parallel and Asynchronous Fixed-Point Iteration for Convex Optimization
Giorgos Stathopoulos, Colin N. Jones
Two characteristics that make convex decomposition algorithms attractive are simplicity of operations and generation of parallelizable structures. In principle, these schemes requi…
Constrained LQR Using Online Decomposition Techniques
L. Ferranti, G. Stathopoulos, C. N. Jones +1
This paper presents an algorithm to solve the infinite horizon constrained linear quadratic regulator (CLQR) problem using operator splitting methods. First, the CLQR problem is re…
Solving the Infinite-horizon Constrained LQR Problem using Accelerated Dual Proximal Methods
Giorgos Stathopoulos, Milan Korda, Colin N. Jones
This work presents an algorithmic scheme for solving the infinite-time constrained linear quadratic regulation problem. We employ an accelerated version of a popular proximal gradi…
Guaranteeing Input Tracking For Constrained Systems: Theory and Application to Demand Response
Tomasz T. Gorecki, Altuğ Bitlislioğlu, Giorgos Stathopoulos +1
A method for certifying exact input trackability for constrained discrete time linear systems is introduced in this paper. A signal is assumed to be drawn from a reference set and…
A hierarchical time-splitting approach for solving finite-time optimal control problems
Georgios Stathopoulos, Tamás Keviczky, Yang Wang
We present a hierarchical computation approach for solving finite-time optimal control problems using operator splitting methods. The first split is performed over the time index a…
