Detailed Description
The biggs_exp6 function is the last of the series, with 6 parameters:
\[ y(x) = \sum^{11}_{i=1} \left(x_3 e^{-0.1i \cdot x_1} - x_4e^{-0.1i \cdot x_2} + x6 e^{-0.1 i \cdot x_5} e^{-0.1i} + 5e^{-i} - 3 e^{-0.4i} \right)^2, \]
subject to \(-20 \le x_i \le 20\), with the global minimum located at \(\mathbf{x}^* = (1,10, 1, 5, 4, 3)\), with \(f(\mathbf{x}^*) = 0\).
Member Function Documentation
◆ evaluate()
|
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.
