Detailed Description

template<>
class MCQMCIntegration::DigitalNet< uint64_t >

Digital Net class for Quasi Mote-Carlo Method.

Explicit specialization for 64-bit unsigned integer.

Constructor & Destructor Documentation

DigitalNet() [1/2]

MCQMCIntegration::DigitalNet< uint64_t >::DigitalNet

(

std::istream &

is

)

constructor from stream.

FORMAT:

• separators are white spaces or newlines.
• 1st element : 64 fixed.
• 2nd element : s, dimension of point set.
• 3rd element : m, F2 dimension of element of point set.
• 4th - : s * m elements of 64-bit integers.
• last but one: WAFOM value, optional.
• last : t-value, optional.

  Exceptions

  runtime_error

  when can't read from stream.

DigitalNet() [2/2]

MCQMCIntegration::DigitalNet< uint64_t >::DigitalNet	(	DigitalNetID	id,
		uint32_t	s,
		uint32_t	m
	)

constructor from pre-defined data.

DigitalNetID:

• NXLW : Niederreiter-Xing low WAFOM up to dimension 10.
• SOBOL: Sobol Point Set up to dimension 21201.
• SOLW : Sobol low WAFOM up to dimension 10.

  Parameters

  [in]	id	ID of pre-defined digital net.
  [in]	s	dimension of point set, s should be 4 <= s
