No, the basic principle is simple:
Any Rules-based Artificial Intelligence system can be modelled as a
sequence of genes, one gene per rule. Thus a simple anti-missile system
might have the rules "Shoot at close targets first" and "Shoot with
missiles rather than guns if you can".
You then make an system-generator, which produces a whole heap of
systems with different rules.
Each of the systems is then put into a simulator, where it must survive
against a variety of threats - say 2 Exocet missiles incoming on one
bearing, then 3 Styx-Cs coming in on separate bearings etc.
Those systems that survive get to breed. But sexually, which means that
the offspring contain 50% of the rules of one parent, and the other 50%
from the other parent. This causes a MASSIVE speed-up of evolution, so
after less than 1000 generations you get a fairly stable population.
Without sexuality, just using random mutation alone, it would take
millions of generations to get the same effect.
There are other details, but I can't really go into those.
