Detailed Description

template<NetConstruction NC, EmbeddingType ET, template< NetConstruction > class OBSERVER = MinimumObserver>
class NetBuilder::Task::Search< NC, ET, OBSERVER >

Virtual base class for search task.

Template Parameters

NC	Net construction type (eg. SOBOL, POLYNOMIAL, EXPLICIT, ...).
ET	Embedding type (UNILEVEL or MULTILEVEL)
OBSERVER	Template template parameter whose template parameter is a net construction type (eg. SOBOL, POLYNOMIAL, EXPLICIT, ...). Should mimick the MinimumObserver class template.

Constructor & Destructor Documentation

Search() [1/3]

template<NetConstruction NC, EmbeddingType ET, template< NetConstruction > class OBSERVER = MinimumObserver>

NetBuilder::Task::Search< NC, ET, OBSERVER >::Search ( Dimension  dimension, typename NetConstructionTraits< NC >::SizeParameter  sizeParameter, int  verbose = 0, bool  earlyAbortion = false  )

inline

Constructor.

Parameters

dimension	Dimension of the searched net.
sizeParameter	Size parameter of the searched net.
verbose	Verbosity level.
earlyAbortion	Early-abortion switch. If true, the computations will be stopped if the net is worse than the best one so far.

Search() [2/3]

template<NetConstruction NC, EmbeddingType ET, template< NetConstruction > class OBSERVER = MinimumObserver>

NetBuilder::Task::Search< NC, ET, OBSERVER >::Search ( Dimension  dimension, std::unique_ptr< DigitalNetConstruction< NC >>  baseNet, int  verbose = 0, bool  earlyAbortion = false  )

inline

Constructor.

Parameters

dimension	Dimension of the searched net.
baseNet	Net from which to start the search.
verbose	Verbosity level.
earlyAbortion	Early-abortion switch. If true, the computations will be stopped if the net is worse than the best one so far.

Search() [3/3]

template<NetConstruction NC, EmbeddingType ET, template< NetConstruction > class OBSERVER = MinimumObserver>

NetBuilder::Task::Search< NC, ET, OBSERVER >::Search ( Search< NC, ET, OBSERVER > &&  )

default
