Wrapper around gsl_min_fminimizer_goldensection

Member Function Documentation

operator()() [1/2]

template<class FUNC >

double theplu::yat::utility::Minimizer::operator() ( FUNC &  func, double  guess, double  min, double  max, Minimizer::Stopper &&  stopper  )

inherited

Function finds an x that minimizes the function defined by func. It calls gsl_min_fminimizer_iterate until there is no progress as defined by stopper.

Type Requirements:

• FUNC must have an operator double operator()(double x)

operator()() [2/2]

template<class FUNC >

double theplu::yat::utility::Minimizer::operator() ( FUNC &  func, double  guess, double  min, double  max, Minimizer::Stopper &&  stopper, unsigned int  max_epochs  )

inherited

Same as operator()(FUNC& func, double guess, double min, double max, Stopper&& stopper); but run at maximum max_epochs epochs (iterations). It is the responsibility of the caller to check if maximum number of epochs has been reached, for example, with the epochs(void function.
