Detailed Description

The biggs_exp3 function is a three-dimensional variation on the previous one, and has the formula

\[ y(x) = \sum^{10}_{i=1} \left(e^{-0.1i \cdot x_1} - x_3e^{-0.1i \cdot x_2} - e^{-0.1i} + 5e^{-i} \right)^2, \]

subject to \(0 \le x_i \le 20\), with the global minimum located at \(\mathbf{x}^* = (1,10, 5)\), with \(f(\mathbf{x}^*) = 0\).

Member Function Documentation

double syn::biggs_exp3::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).
