I've read some recent studies on Darwinist evolution of the computer code, and what is required to make such evolution computationally feasible. Basically, there are two main problems: almost all mutations of a typical piece of code are lethal, and the rewards landscape is too sparse (only goals we care about are rewarded), so the evolutionary process cannot find a "ladder" to climb to the goals. A couple of recent papers present case studies of systems where these problems were sufficiently rectified to enable nontrivial evolution.( Read more... )
