A Linesearch Algorithm with Memory for Unconstrained Optimization [PDF]
This paper considers algorithms for unconstrained nonlinear optimization where the model used by the algorithm to represent the objective function explicitly includes memory of the past iterations. This is intended to make the algorithm less “myopic” in the sense that its behaviour is not completely dominated by the local nature of the objective ...

Modifications of the Limited Memory BFGS Algorithm for Large-scale Nonlinear Optimization [PDF]
In this paper we present two new numerical methods for unconstrained large-scale optimization. These methods apply update formulae, which are derived by considering different techniques of approximating the objective function.

LARGE SCALE UNCONSTRAINED OPTIMIZATION [PDF]
This work is a survey on the methods for large scale unconstrained optimization. Besides its own theoretical importance, the growing interest in the last years in solving problems with a larger and larger number of variables are arising very frequently ...

Robust optimization in simulation: Taguchi and Krige combined [PDF]
Optimization of simulated systems is the goal of many methods, but most methods assume known environments. We, however, develop a "robust" methodology that accounts for uncertain environments.

Globally convergent algorithms for solving unconstrained optimization problems [PDF]
New algorithms for solving unconstrained optimization problems are presented based on the idea of combining two types of descent directions: the direction of anti-gradient and either the Newton or quasi-Newton directions.
