N. Lygeros
A remark about the spirit behind the notion mutation operators.
When we talk about information we have something which is rather like a stable equilibrium even if you change a word.
But for the knowledge, the situation is totally different because we get an unstable equilibrium as each word is important.
For example the following formula exp(iPi)+1=0 is an unstable equilibrium as changes of part of it, destroy its mathematical truth.
