# cut set fn (CutSetFn)

A UnaryFunction that assigns a Graph the Class of GraphPaths that partition the graph into two separate graphs if cut. There may be more than one cutset for a given graph.

## Axioms (3)

minimal cut set fn is internally related to cut set fn.
`(relatedInternalConcept MinimalCutSetFn CutSetFn)`

If graph is an instance of graph, then "the set of minimal paths that partition graph into two separate graphs" is a subclass of "the set of paths that partition graph into two separate graphs".
```(=>
(instance ?GRAPH Graph)
(subclass
(MinimalCutSetFn ?GRAPH)
(CutSetFn ?GRAPH)))```

There don't exist the set of paths that partition graph into two separate graphs path1,the set of minimal paths that partition graph into two separate graphs path2 so that the length of path1 is number1 and the length of path2 is number2 and number1 is less than number2.
```(not
(exists
(?PATH1 ?PATH2)
(and
(instance
?PATH1
(CutSetFn ?GRAPH))
(instance
?PATH2
(MinimalCutSetFn ?GRAPH))
(pathLength ?PATH1 ?NUMBER1)
(pathLength ?PATH2 ?NUMBER2)
(lessThan ?NUMBER1 ?NUMBER2))))```
