Why has no one figured out yet an equation to count the number of unlabeled trees on n vertices?. I also have this dilemma between researchers and non-researchers. A researcher is just someone who is trying to find a solution to a problem for which no solution has been found yet. Right?, so if I try to find this equation, am I already doing research?(adsbygoogle = window.adsbygoogle || []).push({});
