Parallel Newton Methods for Sparse Systems of Nonlinear Equations
In this paper we give the results found in solving consistent sparse systems of nonlinear equations by an inexact Newton and Quasi-Newton method both combined with a block iterative row-projection linear solver of Cimmino-type. A simple partitioning of the Jacobian matrix was used for solving two nonlinear test problems, that is a tridiagonal problem of size n = 131072 and a nonlinear Poisson p...

متن کاملInexact Newton Methods and Mixed Nonlinear Complementary Problems
In this paper we present the results obtained in the solution of sparse and large systems of nonlinear equations by Inexact Newton-like methods [6]. The linearized systems are solved with two preconditioners particularly suited for parallel computation. We report the results for the solution of some nonlinear problems on the CRAY T3E under the MPI environment. Our methods may be used to solve m...
متن کاملA class of multi-agent discrete hybrid non linearizable systems: Optimal controller design based on quasi-Newton algorithm for a class of sign-undefinite hessian cost functions
In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system.
