- Dear Ping and anyone else who agrees with him,
-
- I would like to agree with some of the other responses I have read and
- call you arrogant, but I suspect that you probably get some strange
- sort of pleasure from this so I won't (except that I already did -
- Oh well).
-
- Anyway what I wanted to say was that I think you are being misled by
- the name "Genetic Algorithms" which I consider not to be a very good
- one (am I being arrogant now?). Genetics is only one place where
- evolution is visible. It happens to be one which is perhaps easier
- to analyse in a scientific way than others, but nevertheless if you
- restrict your thoughts to this field only you are shooting yourself
- in the foot.
-
- The genetic model for what could be called "Artificial Evolution"
- imposes unnecessary restrictions on development. If you were to argue
- that it doesn't you'd be arguing that no operation exists which could be
- useful yet is not genetically viable. At the same time you'd also be
- contradicting yourself since evolution is all about trying new things
- and letting variety prosper, and hence you'd be restricting your creativity
- because of some gospel-like belief that genetics is the true model for
- artificial evolution.
-
- Can I suggest that you think of the chromosome (as termed in GAs), not as
- a chromosome but as a representation of an entity, and that this entity
- can be anything which can evolve, be it an economic theory, a political
- system or a biological organism.
-
- I am not discounting the usefulness of the genetic model as a learning
- tool but I am disputing that it be regarded as the "God of Evolution".
