Solution Of Optimal Control Problems By A Pointwise Projected Newton Method

open access: yes, 1995
. In the context of optimal control of ordinary differential equations, we prove local superlinear convergence and constraint identification results for an extension of the projected Newton method of Bertsekas.

Explicit Solutions For Interval Semidefinite Linear Programs

open access: yes, 1993
We consider the special class of semidefinite linear programs (IV P ) maximize trace CX subject to L ¯ A(X) ¯ U; where C; X; L; U are symmetric matrices, A is a (onto) linear operator, and ¯ denotes the Loewner (positive semidefinite) partial order.

Further Development of Minimum Curvature Multi-Step Quasi-Newton Methods for Unconstrained Optimization

open access: yes, 2007
Multi-step quasi-Newton methods for unconstrained optimization were introduced in [1, 2, 3], where it was shown how an interpolation in the variable-space could be used to generalize the Secant Equation.

Comparison Of Different Fictitious Domain Approaches Used In Shape Optimization

open access: yes, 1996
. Shape optimization with a homogeneous Dirichlet boundary value problem as a state is considered. Three fictitious domain approaches on a fixed grid are presented and used as solvers for the state problem.
