Direct search methods: then and now
Journal of Computational and Applied Mathematics, 2000 The authors discuss direct search methods for unconstrained optimization. They discuss how direct search methods are characterized by the absence of the construction of a model of the objective. The article is informative and well-written. It makes a rather pleasant introduction to a very active survey area.

Worst case complexity of direct search
EURO Journal on Computational Optimization, 2013 In this paper, we prove that the broad class of direct-search methods of directional type based on imposing sufficient decrease to accept new iterates shares the worst case complexity bound of steepest descent for the unconstrained minimization of a ...

Memory-Based Evolutionary Algorithms for Nonlinear and Stochastic Programming Problems
Mathematics, 2019 In this paper, we target the problems of finding a global minimum of nonlinear and stochastic programming problems. To solve this type of problem, we propose new approaches based on combining direct search methods with Evolution Strategies (ESs) and ...

Direct Search Methods on Reductive Homogeneous Spaces [PDF]
Journal of Optimization Theory and Applications, 2018 Direct search methods are mainly designed for use in problems with no equality constraints. However, there are many instances where the feasible set is of measure zero in the ambient space and no mesh point lies within it. There are methods for working with feasible sets that are (Riemannian) manifolds, but not all manifolds are created equal.

Equal Angle Distribution of Polling Directions in Direct-Search Methods [PDF]
Journal of Optimization, 2014 The purpose of this paper is twofold: first, to introduce deterministic strategies for directional direct-search methods, including new instances of the mesh adaptive direct-search (MADS) and the generating set search (GSS) class of algorithms, which utilize a nice distribution of PoLLdirections when compared to other strategies, and second, to ...
