Member Function Documentation

operator()() [1/2]

template<class FUNC >

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

inherited

Function finds an x that minimizes the function defined by func. It calls gsl_multimin_fminimizer_iterate until either GSL_ENOPROG is returned or the stopper returns true.

Type Requirements:

• FUNC must have an operator double operator()(const VectorBase& x)

operator()() [2/2]

template<class FUNC >

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

inherited

Same as operator()(yat::utility::VectorMutable&, FUNC& func, Stopper&&); but at maximum run max_epochs epochs (iterations).

step() [1/2]

const yat::utility::Vector& theplu::yat::utility::MultiMinimizer::step ( void  ) const

inherited

The size of the first step.

See also

parameter step_size in gsl_multimin_fminimizer_set

step() [2/2]

yat::utility::Vector& theplu::yat::utility::MultiMinimizer::step ( void  )

inherited

Modify the initial step size.

The size of the vector cannot be modified but must equal the size set in constructor.
