An algorithm for unconstrained optimization

International Journal of Computer Mathematics, 1992
In this note an algorithm for solving unconstrained optimization problems is presented. A convergence analysis for the method is considered too. The rate of convergence is shown to be superlinear. Numerical results are reported.

A View of Unconstrained Optimization.

1987
Abstract : Finding the unconstrained minimizer of a function of more than one variable is an important problem with many practical applications, including data fitting, engineering design, and process control. In addition, techniques for solving unconstrained optimization problems form the basis for most methods for solving constrained optimization ...

Unconstrained Optimization Problems

2010
Unconstrained optimization methods seek a local minimum (or a local maximum) in the absence of restrictions, that is, $$f(x) \longrightarrow \min (x \in D)$$ for a real-valued function f: D → ℝ defined on a nonempty subset D of ℝ n for a given n ∈ ℕ.

Equations and Unconstrained Optimization

2014
In this chapter, we start our discussion of Newton-type methods, which are based on the fundamental principle of linear/quadratic approximation of the problem data (or of some part of the problem data). The underlying idea is extremely important, as it serves as a foundation for numerous computationally efficient algorithms for optimization and ...

Unconstrained Optimization Algorithms

2019
In this chapter, we will present the most representative algorithms for solving an optimization problem without functional constraints, that is, the problem $$ \begin{array}{lll} P: &{} \text {Min} &{} f(x) \\ &{} \text {s.t.} &{} x\in C, \end{array} $$ where \(\emptyset \ne C\subset \mathop {\mathrm {dom}}f\subset \mathbb {R}^{n}.\) We will ...

An incremental decomposition method for unconstrained optimization

Applied Mathematics and Computation, 2014
In this work we consider the problem of minimizing a sum of continuously differentiable functions. The vector of variables is partitioned into two blocks, and we assume that the objective function is convex with respect to a block-component. Problems with this structure arise, for instance, in machine learning.

An Overview of Unconstrained Optimization

1994
Developments in the theory and practice of unconstrained optimization are described. Both line search and trust region prototypes are explained and various algorithms based on the use of a quadratic model are outlined. The properties and implementation of the BFGS method are described in some detail and the current preference for this approach is ...

Few Topics in Unconstrained Optimization

2021
Unconstrained optimization is, on the one hand, a classical topic in optimization, which goes back to the seventeenth century. On the other hand, it is a modern one, which undergone substantial transformation in the last few decades.

Criteria for Unconstrained Global Optimization

Journal of Optimization Theory and Applications, 2007
We develop criteria for the existence and uniqueness of the global minima of a continuous bounded function on a noncompact set. Special attention is given to the problem of parameter estimation via minimization of the sum of squares in nonlinear regression and maximum likelihood.
