Minisymposium 11: First order methods and applications

Time: 15:30 - 17:30
Room: L1.202, Building L
and Organiser: Gerardo Toraldo (Università degli Studi di Napoli Federico II)

Since the  seminal work of Barzilai and Borwein was published in 1988, several new gradient methods have been proposed. These methods appear especially suitable for large scale problems because their low memory and computational cost per iteration. This minisymposium highlights recent developments in the design of first-order methods for constrained and unconstrained minimization, and their  use in practical applications.



15:30 - 16:00Vanna Lisa Coli (Universita  di Modena e Reggio Emilia): First-order scaled methods for image reconstruction in X-rays Computed Tomography
16:00 - 16:30Marco Viola (Universita di Roma la Sapienza): P2GP: a proportioning-based two-phase gradient algorithm for QP problems with bounds on the variables and a linear constraint
16:30 - 17:00Oldrich Vlach (Technical University of Ostrava): QP algorithms with rate of convergence and applications
