Prolog
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.
Formulate the appropriate Prolog rule
"connection(X,Y)" which is true if (and only if) there is a
"connection" from "X" to "Y" as described above --- note that this
rule will be recursive. Test this rule out on the above network, to
see if it is working correctly.
Once it is working correctly, you will note that, e.g., the query
"connection(a,e)." will give "true" multiple times. This means
something, actually:
