Detailed Description
template<typename U, typename V = U>
class MTToolBox::EquidistributionCalculatable< U, V >
This class is an Abstract class for calculating dimension of equi-distribution for GF(2)-linear pseudo random number generators.
- Template Parameters
-
U type of output of pseudo random number generator, should be unsinged number. V type of oiutput of parameter generator.

Add internal state of GF(2)-linear pseudo random number generators.
- Warning
- When keeping internal state in an array and using index for round robbin, adding shoud be relative to index like:
for (int i = 0; i < size; i++) { state[(index + i) % size] ^= that.state[(that.index + i) % size]; }

output outBitLen from MSB.
Remained bits should be all zeros. Users should call statte transition function inside this method.
- Parameters
-
[in] outBitLen Shows how many bits are outputed.
- Returns
- an integer whose outBiteLen bits from MSB.

pure virtual |
Check if bits in internal state are all zero.
When using an incomplete array like Mersenne Twister, user should check bits in true internal state.
|
pure virtual |
Set all zero to internal state.
