well, mutation of random number of bits, interesting idea) let's say you chose to change from 8 to 20 and it randomly drives you this piece of bits)
It is possible to create various variations. You can generate four different XOR masks at once to be bit-flipped using AVX2.
I mean, I'll enter it as a range, when starting the program we now do -f 8 (for example), and there, for example, -f 8:10 was set, and flips (they are done randomly between 8 and 10 bits, they can change 8 in the iteration, and another 9, and so on
