// We omit the chen* functions on the basis that they are difficult to // calculate leading to floating-point errors. When we are given control over // the experimental design, we can constrain our optimisations to values which // are easily represented by floating-point values; henc ethese benchmarks can // be considered somewhat unrealistic.

◆ 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.
