If the undirected version G ′ of the DAG G = ( V, E) is not connected, then there is no polytree that contains all vertices in V and only a subset of the edges in E. If G ′ is connected, then you can compute any spanning tree T of G ′ and construct the poly-tree that contains all vertices in V plus all the ...

Webdirected graph is acyclic if it has no cycles. In this case we say that the graph is a directed acyclic graph or DAG. From now on, we only deal with directed acyclic graphs since it is very difficult to provide a coherent probability semantics over graphs with directed cycles. 18.3 Probability and DAGs Let G be a DAG with vertices V =(X 1 ...
