It does +not affect the stream produced using ``RandomState`` or ``MT19937`` that +are directly seeded. + +The translation of the jumping code for the MT19937 contained a reversed loop +ordering. ``MT19937.jumped`` matches the Makoto Matsumoto's original +implementation of the Horner and Sliding Window jump methods. |
