Exponential Function

Description

This scalable test function is based on the definition

f(\mathbf{x}) = -\exp\left(-0.5 \sum_{i = 1}^{n} \mathbf{x}_i^2\right)

with the box-constraints \mathbf{x}_i \in [-1, 1], i = 1, \ldots, n.

Usage

makeExponentialFunction(dimensions)

Arguments

dimensions

[integer(1)]
Size of corresponding parameter space.

Value

[smoof_single_objective_function]
