Member Function Documentation

operator()() [1/2]

template<class FUNC >

void theplu::yat::utility::MultiMinimizerDerivative::operator() ( yat::utility::VectorMutable &  x, FUNC &  func, MultiMinimizerDerivative::Stopper &&  stopper  )

inherited

Function finds an x that minimizes the function defined by func. It calls gsl_multimin_fdfminimizer_iterate until either GSL_ENOPROG is returned or the norm of the gradient is smaller than epsabs, as tested by gsl_multimin_test_gradient.

Type Requirements:

• FUNC must have an operator defining the function double operator()(const VectorBase& x)
• FUNC must have an operator defining the gradient void operator()(const VectorBase& x, VectorMutable&)

operator()() [2/2]

template<class FUNC >

void theplu::yat::utility::MultiMinimizerDerivative::operator() ( yat::utility::VectorMutable &  x, FUNC &  func, MultiMinimizerDerivative::Stopper &&  stopper, unsigned int  max_epochs  )

inherited

Same as operator()(yat::utility::VectorMutable&, FUNC& func, double epsabs) but iterate at maximum max_epochs iterations.

step_size() [1/2]

double theplu::yat::utility::MultiMinimizerDerivative::step_size ( void  ) const

inherited

The size of the first trial step is given by step_size

step_size() [2/2]

void theplu::yat::utility::MultiMinimizerDerivative::step_size ( double  ss )

inherited

tolerance() [1/2]

double theplu::yat::utility::MultiMinimizerDerivative::tolerance ( void  ) const

inherited

The accuracy of the line minimization is specified by tolerance
