| Jan 7, 2022 at 8:48 | comment | added | wzkchem5 | @NikeDattani Yes of course. I was mentioning P=NP simply because this is much more well-known, and the amount of prize money for proving P=NP is also very well-known :) | |
| Jan 7, 2022 at 5:05 | comment | added | Nike Dattani - No Free Time | @wzkchem5 I think they would also have proven not only that P = NP, but also that NP = QMA. Considering how many quantum computing algorithms we know to be in QMA but don't know to be in NP, I'd be quite surprised and astonished if someone were to prove that NP = QMA, whereas P=NP wouldn't be too surprising for some people (for example Donald Knuth still seemed to lean in this favor as recently as 2018 when he most recently visited my city). | |

The exact functional will only be a Nobel prize-level discovery if it is significantly cheaper than basis set extrapolated approximate full CI methods, or more or less equivalently, if it is not significantly more expensive than contemporary approximate functionals. But this is very unlikely. In particular, if the exact functional can be evaluated in polynomial time, the discoverer can get another $1,000,000 from the Clay Institute, due to the result implying P=NP. | |
