NFL theorem is frankly silly.
It boils down to "you can't predict random numbers".
I'm sure it's useful to have formalized but it has no real impact on real world situations because most problems we care about have some kind of structure we can exploit.
- nextaccountic 3y agoWell when I asked "How does the worst case for an algorithm like this look like?" I fully expected the answer to be "in practice this never happens" (that is, there are bad cases but since we aren't drawing inputs at random, in practice we never hit them) But how likely is that?
