Web1 jun. 2024 · Factor graphs are a class of graphical models in which there are variables and factors. The variables represent unknown quantities in the problem, and the factors represent functions on subsets of the variables. WebIf His a factor graph, define an assignment ˘of Hto be a mapping from nodes to values: ˘(v) 2 (v). We write Hfor the set of all assignments of H. The weight of an assignment ˘is given by w H(˘) = Y edges e with att(e) = v 1 v k F(e)(˘(v 1);:::;˘(v k)): In a factor graph with no factors, every assignment has weight 1. A factor graph with ...

It says that K 2 n + 1 has a decomposition in n Hamiltonian cycles and K 2 n has a decomposition in n − 1 Hamiltonian cycles and a perfect matching. This means that for even n you can build any factor you like. matlab plot show data pointsWebIf a connected graph is 2 k -regular it may be k -factored, by choosing each of the two factors to be an alternating subset of the edges of an Euler tour.
