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.

The complex mechanism of the method makes theoretical analysis difficult. Therefore, simplified versions of RF, called purely RFs (PRF), which can be theoretically handled more easily, have been considered. flower shops in muskogee
