# Do any single-cell organisms exist that approximate NP-hard problems within a factor better than \$1/2\$ \$log\$2?

I’ve seen on Wikipedia; that set covering cannot be approximated in polynomial time to within a factor mentioned above. Unless $$NP$$ has quasipoly-time algorithms.

Now, this must pertain to classical algorithms and does not mention any approximation algorithms that may only work in nature.

(eg. Things like Amoebas solving $$TSP$$ problems)

• Do any single-cell organisms show any promise in solving $$NP$$-hard problems in polynomial-time?

• Or approximating them better than any known classical algorithms?
