WebReversible linear congruential generator (lcg) As multiple people have pointed out, an lcg is indeed reversible. In an lcg, the next state is computed like this: x = (a * prevx + c) mod m. We can reorder this: x ≡ a * prevx + c (mod m) x - c ≡ a * prevx (mod m) Since a and m are chosen to be relatively prime in an lcg, we can find the ...
