public class WELL512
WELL512
This class implements the RandomStream interface via inheritance from RandomStreamBase. The backbone generator is a Well Equidistributed Long period Linear Random Number Generator (WELL), proposed by F. Panneton, and which has a state size of 512 bits and a period length of approximatively 2512. The values of V, W and Z are 2150, 2200 and 2350 respectively (see RandomStream for their definition). The seed of the RNG, and the state of a stream at any given step, is a 16-dimensional vector of 32-bit integers.

resetNextSubstream()
Reinitializes the stream to the beginning of its next substream: Ng is computed, and Cg and Bg are set to Ng. |
void |
resetStartStream()
Reinitializes the stream to its initial state Ig: Cg and Bg are set to Ig. |
void |
resetStartSubstream()
Reinitializes the stream to the beginning of its current substream: Cg is set to Bg. |
