I read that on the GitHub page but I am still having a hard time imagining that those changes weaken the function enough to become attackable by a genetic algorithm. According to my intuition even relatively weak cryptographic functions should be pretty hard to tackle by genetic algorithms due to the complex structure of the search space with many extrema. Maybe I will have a closer look tomorrow, I am starting to get really curious.
