It is well-known just as Ackley's Function [1-10], and sometimes as Ackley's Path Function [11]. Because there are some modified ... WebJul 30, 2015 · This is why we call it Dixon-Price-Rosenbrock's Function. Based on that, we can consider the other suggested side constraints of Rosenbrock's Function to be used for this new benchmark function. Although it is expressed as a 2 − dimensional problem in [1], the generalized version is expressed in [2] for any higher dimension.

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]
