Detailed Description

The Dolan function has the following formula:

\[ f(\mathbf{x}) = \left(x_1+1.7x_2\right)\sin\left(x_1\right)-1.5x_3-0.1x_4 \cos\left(x_5+x_4-x_1\right)+0.2x_5^2-x_2-1 \]

subject to \(-100 \le x_i \le 100\). There is a global minimum at \(\mathbf{x}^* = (98.964258312237106,100,100,99.224323672554704,−0.249987527588471)\) with value \(f(\mathbf{x}^*) = −529.8714387324576\).

Member Function Documentation

evaluate()

double syn::dolan::evaluate ( inst::set  x )

overridevirtual

Evaluate the benchmark (i.e. calculate the value of the objective fuinction) on the provided values.

Parameters

x	A vector of double-precision values to evaluate the benchmark at.

Todo:

Verify that a vector of doubles does not constrict the range of benchmark functions which may be evaluated (i.e. as opposed to categorical variables such as strings).

Implements optk::benchmark.
