Similarly: In theory, the protein folding problem \(predicting the lowest\-energy configuration for a string of amino acids\) is NP\-hard \(sorta\)\. But since quantum mechanics is not known to solve NP\-hard problems, this just means that in the real world, biology is happy with just picking out proteins that reliably fold up a particular way \(even if it's not the ideal lowest energy\)\. "NP\-hard" problems in real life with nonrandom data often have regularities that make them much more easily solvable than the worst cases; or they have pretty good approximate solutions; or we can work with just the solvable cases\.

This is interesting! Is there a name for this concept / area of thought?
