  1. 1. Distributed Optimization and Control : Primal--Dual, Online, and Event-Triggered Algorithms

    Author : Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. READ MORE

  2. 2. Novel Hessian approximations in optimization algorithms

    Author : Erik Berglund; Mikael Johansson; Pontus Giselsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : There are several benefits of taking the Hessian of the objective function into account when designing optimization algorithms. Compared to using strictly gradient-based algorithms, Hessian-based algorithms usually require fewer iterations to converge. READ MORE
