makeKursaweFunction {smoof}

Kursawe Function

Description

Builds and returns the bi-objective Kursawe test problem.

The Kursawe test problem is defined as follows:

Minimize f_1(\mathbf{x}) = \sum\limits_{i = 1}^{n - 1} (-10 \cdot \exp(-0.2 \cdot \sqrt{x_i^2 + x_{i + 1}^2})),

Minimize f_2(\mathbf{x}) = \sum\limits_{i = 1}^{n} ( |x_i|^{0.8} + 5 \cdot \sin^3(x_i)),

with -5 \leq x_i \leq 5, for i = 1, 2, \ldots, n,.

Usage

makeKursaweFunction(dimensions)

Arguments

Value
