Functions

base_epistasis

inline void ioh::problem::utils::base_epistasis(const std::vector<int> &xIn, const int start, const int nu, std::vector<int> &xOut)

dummy

inline std::vector<int> ioh::problem::utils::dummy(const int n_variables, const double select_rate, const long seed)

Returns a set of indices selected randomly from the range [0, n_variables].

Selects floor(n_variables * select_rate) indices with replacement.

Parameters:

• n_variables – The range of the index

• select_rate – The probability of selection for any given index.

• seed – The random seed for the random number generator

Returns:

A list of selected indices, in ascending order.
