....to classical tree enumeration, where the generating functions typically have only algebraic singularities. To oversimplify a little, it can be said that at least asymptotic enumeration of unlabeled trees of various kinds is very well understood. The basic method used there was developed by Polya [32] and perfected by Otter [31] Their method is presented also in [16] and it is so well understood that a few years ago a paper was written with the title Twenty step algorithm for determining the asymptotic number of trees of various species [17] The word algorithm in the title of that ....
