A directed

acyclic graph is built which directs the flow of packets and ensures its reachability to all the other nodes.

Complex extract, transform, load (ETL) can be done by either chaining scripts together so that the output of one is the input to another or using a workflow engine like Apache Oozie with actions arranged in directed

acyclic graph (DAG) to gate actions.

Definition: (Semantic Relationship Graph) Semantic Relationship Graph is a directed

acyclic graph SRG (V, E, W), where V is a set of vertices, each of which corresponding to a table in the database.

The intruder pits against the greens, who form a directed

acyclic graph, with one source (the top of the volcano) and many sinks representing the lake.

In contrast to classification and regression, where the output is a single scalar value, in our case the output is a data structure, such as a tuple or a directed

acyclic graph.

Semantic Nets-In Semantic Nets the knowledge is represented by a Directed

Acyclic Graph (DAG).

In [18], [3], [5], [6], and [22] other strategy are used to construct feature set, such as graph closure, directed

acyclic graph decomposition, special components in graph.

To have an

acyclic graph of precedence relations, we must compute the weight of all phases and reciprocally, if there is a phase whose weight can't be computed, the graph is cyclic (Swamidass, 2002).

Combinational part of a general logic network N can be represented as a direct

acyclic graph (DAG) noted as N(V, E) where V is the set of nodes and E is the set of directed edges.

Specifically, if G is a directed

acyclic graph with variable set V, and if X and Y are in V, and Z is also in V, then the implied linear correlation between X and Y in G, conditional on Z, is 0 if and only if X and Y are d-separated given Z.

i] being one of six kinds: an oriented

acyclic graph, a clique, an independent set, a chain, a reflexive clique, or an antichain.

Note that we use tree in broader sense as a graph rather than restricting its definition to

acyclic graph.
