Detailed Description

template<typename U, typename V = U>
class MTToolBox::AlgorithmTempering< U, V >

Algorithm that search tempering parameters to improve dimension of equi-distribution of output of pseudo random number generator.

Warning

If you could not get high dimension of equi-distribution after tempering using parameters got by this algorithm, you should consider changing the design of random number generation algorithm.

Template Parameters

U	type of output of pseudo random number generator, for example, uint32_t. Only unsigned numbers are allowed.
V	type of parameter generator

Shows if searching tempering parameters is from LSBs.

Returns

true if searching is from LSBs.

Reimplemented in MTToolBox::AlgorithmBestBits< U, V >, and MTToolBox::AlgorithmPartialBitPattern< U, V, bit_len, param_num, try_bit_len, step, lsb >.

template<typename U, typename V = U>

virtual int MTToolBox::AlgorithmTempering< U, V >::operator() ( TemperingCalculatable< U, V > &  rand, bool  verbose = false  )

pure virtual

Search tempering parameters.

Searched parameters are set to rand. This process may consume large CPU time.

Parameters

rand	pseudo random number generator
verbose	if true output redundant messages.

Returns

always zero.

Implemented in MTToolBox::AlgorithmBestBits< U, V >, and MTToolBox::AlgorithmPartialBitPattern< U, V, bit_len, param_num, try_bit_len, step, lsb >.
