- This is a poor analogy for evolution or abiogenesis (which ever one you're
- attempting to analyse here). A chess program does not reproduce.
- No form of natural selection is applied to it.

- This has all the flaws of the first example plus one: it is more unlikely
- to satify a path of mutations when the target is specified in advance.
