Chemists have created a network database of all the chemical knowledge about organic chemistry right now; they can create any number of algorithms to solve whatever problems using all the known chemistry rules humanity has dug up over the last two hundred and fifty years!  That alone is a great accomplishment.  Nanotechnologists have been linking and posting about this as an automated engineering technology to probably make nano-mechanical parts.
