Solution Summary: The author illustrates how the diagraph is drawn using a given vertex-set and an arc set.
a. Draw a digraph with vertex-set
V
=
{
A
,
B
,
C
,
D
}
and arc-set
A
=
{
AB
,
AC
,
AD
,
BD
,
DB
}
.
b. Draw a digraph with vertex-set
V
=
{
A
,
B
,
C
,
D
,
E
}
and arc- set
A
=
{
AC
,
AE
,
BE
,
CD
,
DC
,
ED
}
.
c. Draw a digraph with vertex-set
V
=
{
W
,
X
,
Y
,
Z
}
and such that W is incident to X and Y, X is incident to Y and Z, Y is incident to Z and W, and Z is incident to W and X.
