Detailed Description

The Griewank function has many widespread local minima, which are regularly distributed.

Its optimal parameter = (0, ..., 0) and optimal function value = 0.

\[ f(x_1 \cdots x_n) = 1 + \frac{1}{4000} \sum_{i=1}^n x^2_i - \prod_{i=1}^n cos(\frac{x_i}{\sqrt{i}}) \]

\[ -600.00 \leq x_i \leq 6.00 \]

\[ \text{minimum at }f(0, \cdots, 0) = 0 \]

Constructor & Destructor Documentation

pass::griewank_function::griewank_function ( const arma::uword dimension )

explicit

Initialises a Griewank function with dimension dimensions, lower bounds of -600.0 and upper bounds of 600.0.

double pass::griewank_function::evaluate ( const arma::vec & agent ) const

overridevirtual
