A Linesearch Algorithm With Memory for Unconstrained Optimization [PDF]

open access: yes, 1998
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&

Testing Unconstrained Optimization Software [PDF]

open access: yesACM Transactions on Mathematical Software, 1981
Much of the testing of optimization software is inadequate because the number of test functmns is small or the starting points are close to the solution. In addition, there has been too much emphasm on measurmg the efficmncy of the software and not enough on testing reliability and robustness.

Robust optimization in simulation: Taguchi and Krige combined [PDF]

open access: yes, 2011
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.

On the hardness of quadratic unconstrained binary optimization problems [PDF]

open access: yes, 2022
We use exact enumeration to characterize the solutions of quadratic unconstrained binary optimization problems of less than 21 variables in terms of their distributions of Hamming distances to close-by solutions.

Higher-Order Optimality Conditions for Degenerate Unconstrained Optimization Problems

open access: yes, 2022
In this paper necessary and sufficient conditions of a minimum for the unconstrained degenerate optimization problem are presented. These conditions generalize the well-known optimality conditions.

Modifications of the Limited Memory BFGS Algorithm for Large-scale Nonlinear Optimization

open access: yes, 2005
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

open access: yes, 2009
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 ...

A Comparison between Fixed-Basis and Variable-Basis Schemes for Function Approximation and Functional Optimization [PDF]

open access: yes, 2012
Fixed-basis and variable-basis approximation schemes are compared for the problems of function approximation and functional optimization (also known as infinite programming).

Globally convergent algorithms for solving unconstrained optimization problems

open access: yes, 2013
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.
