The issue is that its still a massive search space.

You can do this yourself, go play nandgame, and beat it, at which point you should be able to make a cpu out of nandgates. Then set up a rnn that is the same layers at total layers of the nandgates and as wide as all the inputs, with every output being fed back into the first input. Then do PSO or GA on all the weights and see how long it takes you to make a fully functioning cpu.
