This is trash-from practical point of view, but there is ambutious mathematic thought.
Return to the reality.

That is not an impossible approach but one must examine that program carefully. Still, trial and error will remain a valid and necessary approach for accumulation of knowledge that may help devising of such programs and enhancement of the other approach.

Read the web-available article copy. What’s so fascinating in it? Such approach is a routine, e.g. when optimizing parameters for semi-empirical quantum mechanics approach or any empirical force fields (MM* et al).

Hi A Khavryuchenko,

I believe that you can get the article here:

This must be a candidate for worst science press release of the year. I've done my best to explain it on Soft Machines.

Can someone post a pdf of the article? Thanks in advance.

I saw a post here about this:

Wondering now if I was naive to just nod along with the minimax talk about ‘optimization,’ whereby the optimal output of a system (costs/benefits) can be modeled.

Me too, only a novice. Haven’t purchased the article, but I would think this might allow the self-assembly of graphene sheets or maybe even diamond lattices under the right conditions.

I’m just a novice but I’ll take a stab at it. I believe the article is saying that when a researcher is trying to make something useful by means of self-assembly it is usually a tedious process of trial and error. It probably has to do with make changes in things like time, pressure and temperature during the assembly process and then examining the final results. What Torquato has done is create a computer program where you input your desired result and the program tell you the process to achieve it.
