children -- returns the children of a vertex of a digraph

Synopsis

Usage:

C = children (D, v)
Inputs:
- D, an instance of the type Digraph,
- v, a thing, the vertex that we want to find the children of
Outputs:
- C, a set, a set of the children of v

Description

The children of v are the all the vertices u such that {v,u} is in the edge set of the digraph D. So the children of a vertex v are exactly those vertices on a directed graph that v points to.

i1 : D = digraph({a,b,c,d,e},{{a,b},{b,c},{b,d},{e,b}});

i2 : children(D, b)

o2 = set {c, d}

o2 : Set
