Consider the (directed) network in the attached document We could represent this network with the following Prolog statements: link(a,b). link(a,c). link(b,c). link(b,d). link(c,d). link(d,e). link(d,f). link(e,f). link(f,g). Now, given this network, we say that there is a "connection" from a node "X" to a node "y" if we can get from "X" to "Y" via a series of links, for example, in this network, there is a connection from "a" to "d", and a connection from "c" to "f", etc.

Question
Consider the (directed) network in the attached document We
could represent this network with the following Prolog statements:
link(a,b).
link(a,c).
link(b,c).
link(b,d).
link(c,d).
link(d,e).
link(d,f).
link(e,f).
link(f,g).
Now, given this network, we say that there is a "connection" from a
node "X" to a node "y" if we can get from "X" to "Y" via a series of
links, for example, in this network, there is a connection from "a" to
"d", and a connection from "c" to "f", etc.
