terminal node fn (TerminalNodeFn)

A UnaryFunction that maps a GraphArc to the terminal node of the GraphArc. Note that this is a partial function. In particular, the function is undefined for GraphArcs that are not part of a DirectedGraph.

Axioms (4)

Se graph é un' istanza di GrafoDiretto e arc é un' istanza di ArcoDelGrafo e arc é una parte di graph, allora esiste node1,node2 tale che "il nodo iniziale di arc" is uguale a node1 e "il nodo terminale di arc" is uguale a node2.
```(=>
(and
(instance ?GRAPH DirectedGraph)
(instance ?ARC GraphArc)
(graphPart ?ARC ?GRAPH))
(exists
(?NODE1 ?NODE2)
(and
(equal
(InitialNodeFn ?ARC)
?NODE1)
(equal
(TerminalNodeFn ?ARC)
?NODE2))))```

```(=>
(and
(instance ?GRAPH GraphPath)
(instance ?ARC GraphArc)
(graphPart ?ARC ?GRAPH))
(=>
(equal
(TerminalNodeFn ?ARC)
?NODE)
(not
(exists
(?OTHER)
(and
(equal
(TerminalNodeFn ?OTHER)
?NODE)
(not
(equal ?OTHER ?ARC)))))))```

Se "il nodo iniziale di arc" is uguale a node e "il nodo terminale di arc" is uguale a node, allora arc é un' istanza di GrafoCiclico.
```(=>
(and
(equal
(InitialNodeFn ?ARC)
?NODE)
(equal
(TerminalNodeFn ?ARC)
?NODE))
(instance ?ARC GraphLoop))```

end node fn é interamente correlato a terminal node fn.
