Stochastic economic model predictive control for Markovian switching systems
Pantelis Sopasakis, Domagoj Herceg, Panagiotis Patrinos +1
The optimization of process economics within the model predictive control (MPC) formulation has given rise to a new control paradigm known as economic MPC (EMPC). Several authors h…
SuperMann: a superlinearly convergent algorithm for finding fixed points of nonexpansive operators
Andreas Themelis, Panagiotis Patrinos
Operator splitting techniques have recently gained popularity in convex optimization problems arising in various control fields. Being fixed-point iterations of nonexpansive operat…
Forward-backward envelope for the sum of two nonconvex functions: Further properties and nonmonotone line-search algorithms
Andreas Themelis, Lorenzo Stella, Panagiotis Patrinos
We propose ZeroFPR, a nonmonotone linesearch algorithm for minimizing the sum of two nonconvex functions, one of which is smooth and the other possibly nonsmooth. ZeroFPR is the fi…
Accelerated reconstruction of a compressively sampled data stream
Pantelis Sopasakis, Nikolaos Freris, Panagiotis Patrinos
The traditional compressed sensing approach is naturally offline, in that it amounts to sparsely sampling and reconstructing a given dataset. Recently, an online algorithm for perf…
Forward-backward quasi-Newton methods for nonsmooth optimization problems
Lorenzo Stella, Andreas Themelis, Panagiotis Patrinos
The forward-backward splitting method (FBS) for minimizing a nonsmooth composite function can be interpreted as a (variable-metric) gradient method over a continuously differentiab…
New Primal-Dual Proximal Algorithm for Distributed Optimization
Puya Latafat, Lorenzo Stella, Panagiotis Patrinos
We consider a network of agents, each with its own private cost consisting of the sum of two possibly nonsmooth convex functions, one of which is composed with a linear operator. A…
