WebAug 1, 2004 · We provide an asymptotic formula for the number of labelled essential DAGs an and show that lim n→∞an′ / an = c, where an′ is the number of labelled DAGs and c ≈13.65, which is interesting in the field of Bayesian networks. Furthermore, we present an asymptotic formula for the number of labelled chain graphs. Index Terms

WebThe enumeration of forests of different orders in a graph is carried out by a procedure that involves formal sums and certain annihilation operators on the space of such sums. The results here extend the well-known matrix-tree theorem to the general case of forests. Introduction.
