A very abstract way to say it is..
1) greedy search doesn't work for this kind of application, you need to find
complex patterns whose component parts are not simple patterns
2) evolutionary search won't work because the problem space is too big
3) you need, in some way, to use some type of reasoning to guide various
phases of search [e.g. you search for good sets of genes, in a non-greedy
way, but where "goodness" is defined by the results of another search, for
prob. logical patterns binding together the set of genes]
Now you can do this sort of thing by tying together variants traditional AI
methods, but an useful *way* of tying them together is apparently hard to
come up with, unless you have an overall framework like novamente to guide
the tying-together process...

yes to both

No, it hasn't learned any of its own heuristics at this point

Yes, this is of course true, but this is also true for NN's and GA's ...
