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 ... WebAlgorithms for directed acyclic graphs (DAGs). Note that most of these functions are only guaranteed to work for DAGs. In general, these functions do not check for acyclic-ness, so it is up to the user to check for that.
