| A C-program for MT19937-64 (2004/9/29 version). |
| Coded by Takuji Nishimura and Makoto Matsumoto. |
| |
| This is a 64-bit version of Mersenne Twister pseudorandom number |
| generator. |
| |
| Before using, initialize the state by using init_genrand64(seed) |
| or init_by_array64(init_key, key_length). |
