Direct search methods for influence maximization problems [PDF]
, 2023 openThe influence maximization problem seeks to maximize the spread of influence in network structures. This challenging optimization task remains unsolved due to its combinatorial nature and computational complexity. In this thesis, we propose two novel

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 ...

Stochastic Direct Search Method for Blind Resource Allocation
Trans. Mach. Learn. Res., 2022 Motivated by programmatic advertising optimization, we consider the task of sequentially allocating budget across a set of resources. At every time step, a feasible allocation is chosen and only a corresponding random return is observed. The goal is to maximize the cumulative expected sum of returns.

Parallel Optimization Methods Based on Direct Search [PDF]
, 2006 This paper is focused in the parallelization of Direct Search Optimization methods, which are part of the family of derivative-free methods. These methods are known to be quite slow, but are easily parallelizable, and have the advantage of achieving global convergence in some problems where standard Newton-like methods (based on derivatives) fail ...

Directed search methods for surface structure determination by LEED [PDF]
Surface Science, 1990 Conventional surface crystallography by low-energy electron diffraction employs a trial-and-error search controlled at each step by a human being. This trial-and-error approach becomes very cumbersome and unreliable when it is applied to complex surfaces with a large number of unknown structural parameters.
