An estimation of the condition number for a class of indefinite preconditioned matrices

Fasano, Giovanni; Roma, Massimo - Dipartimento di Ingegneria Informatica, Automatica e … - 2015

We propose a class of preconditioners for symmetric linear systems arising from numerical analysis and nonconvex … optimization frameworks. Our preconditioners are specifically suited for large indefinite linear systems and may be obtained as by … of a sequence of linear systems, say Ax = bi or Aix = bi, where respectively the right-hand side changes or the system …

Initial particles position for PSO, in Bound Constrained Optimization

Campana, E.F.; Diez, Matteo; Fasano, Giovanni; Peri, Daniele - Dipartimento di Management, Università Ca' Foscari Venezia - 2013

We consider the solution of bound constrained optimization problems, where we assume that the evaluation of the objective function is costly, its derivatives are unavailable and the use of exact derivativefree algorithms may imply a too large computational burden. There is plenty of real...

Introduction to Control Systems Design Using Matlab

Azar, Ahmad Taher; Moysis, Lazaros; Kafetzis, Ioannis; … - In: International Journal of System Dynamics Applications … 6 (2017) 3, pp. 130-170

Control systems theory is a wide area covering a range of artificial and physical phenomena. Control systems are systems that are designed to operate under strict specifications, to satisfy certain aims, like safety regulations in the industry, optimal production of goods, disturbance rejection...
