I assumed all new breakthroughs in advanced complexity theory would be theoretical and non-constructive, as in "we prove that this algorithm must exist but we do not provide it".
I'm genuinely shook at today's results, specially at the fact that there _is_ a constructive algorithm.
Polynomial is something like exp(n log x), where x is the problem size. Exponential is something like exp(x). Superpolynomial but subexponential is roughly when the exponent is between n log x and x. An exponent of (log x)^2 would do the trick.
