WebOct 18, 2024 · How does MT19937 PRNG work? MT can be considered as a twisted form of the generalized Linear-feedback shift register (LFSR). The idea of LFSR is to use a linear function, such as XOR, with the old register value to get the register’s new value. In MT, the internal state is saved in the form of a sequence of 32-bit words.
