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 ...

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.

Optimization by Direct Search in Matrix Computations [PDF]
SIAM Journal on Matrix Analysis and Applications, 1993 Many questions about algorithms in matrix computations can be expressed in terms of the maximum value of some easily computable function \(f\). For many algorithms it is known that direct search is capable of revealing instability or proof performance.

Directed Search with Phantom Vacancies [PDF]
SSRN Electronic Journal, 2020 AbstractWhen vacancies are filled, the job ads often remain, creating phantom vacancies. Older listings more likely represent phantoms. We assume job seekers direct their search based on listing age. Forming a match with an age‐a vacancy creates an age‐a phantom with probability β and generates an externality affecting vacancies aged a and older. Thus,
