Pure random search

Random search (RS) is a family of numerical optimization methods that do not require the gradient of the problem to be optimized, and RS can hence be used on functions that are not continuous or differentiable. Such optimization methods are also known as direct-search, derivative-free, or black-box methods. Anderson … See more Let f: ℝ → ℝ be the fitness or cost function which must be minimized. Let x ∈ ℝ designate a position or candidate solution in the search-space. The basic RS algorithm can then be described as: 1. Initialize … See more Truly random search is purely by luck and varies from very costive to very lucky, but the structured random search is strategic. A number of RS variants have been introduced in the … See more • Random optimization is a closely related family of optimization methods which sample from a normal distribution instead of a hypersphere. • Luus–Jaakola is a closely related optimization method using a uniform distribution in its sampling and a simple formula for … See more WebPure Random Search from publication: Global optimization using local searches Local Search ResearchGate, the professional network for scientists.

WebPure random search samples points from the domain independently, and the objective function has no impact on the technique of generating the next sample point. In contrast, … WebThe pure random search, already discussed in the late 1950s by Brooks [4], is the simplest stochastic search algo-rithm and shall serve as a baseline algorithm in any bench-marking experiment. The algorithm samples each candidate solution independently and uniformly at random within a xed search domain and returns the best solution found.
