The actual hash computation should be mechanical. It's a straight algorithm. The part you want to optimize is the selection of the random noise you need to make the hash come out with the appropriate number of zeros. You ask your test subjects (monkey, human, slime mold, whatever) to provide the noise, you test it with your mechanical hasher, and then either reward or punish them based on the number zeros in the hash.
