WebIn mathematical optimization, the Rastrigin function is a non- convex function used as a performance test problem for optimization algorithms. It is a typical example of non-linear multimodal function. It was first proposed in 1974 by Rastrigin [1] as a 2-dimensional function and has been generalized by Rudolph. [2] WebFor example, a generalized Rosenbrock's function can have extra parameters representing the constants 100 and 1: f ( x , a , b ) = a ( x 1 2 - x 2 ) 2 + ( b - x 1 ) 2 . a and b are parameters to the fitness function that act as constants during the optimization (they are not varied as part of the minimization).

WebMay 11, 2014 · The Broyden-Fletcher-Goldfarb-Shanno (BFGS) method typically requires fewer function calls than the simplex algorithm even when the gradient must be estimated. To demonstrate this algorithm, the Rosenbrock function is again used. The gradient of the Rosenbrock function is the vector: This expression is valid for the interior derivatives.
