[galib] Quick question on mutation probability

If pMut = 0.01 and my binary string has a length of 200 bits. That means
that at least two bits are always mutating on every chromosome?
There is no chromosome that exhibits no change?
Isn't that bad?
If I am correct, the pMut should be proportional to the string size.
"About 60 million transistors were built this year just for you, with
another 60 million for each of your friends, plus 60 million for every
other man, woman, and child on Earth. By 2010, the number should be
around one billion transistors per person per year. "

I don't know if this will suit my needs, but I'm very willing to look
at it tomorrow. Thanks greatly for suggesting it!
