Then the counting series are derived for undirected unlabeled and labeled hypergraphs, thus the isomorphism and counting problems of undirected hypergraphs are solved.
However, reasoning on student model is a NP hard question in fact, since undirected loops are embedded in the Bayesian student model.
And yet the rage that one felt was an abstract, undirected emotion which could be switched from one object to another like the flame of a blowlamp.
