Your Assignment:
1. Given the relations
father(X,Y) X is the father of Y
mother(X, Y) X is the mother of Y
female(X) X is female
male(X ) X is male
Define prolog relations for the following:
a. sibling
b. sister
c. grandson
d. descendant
Provide some facts for the father, mother, male, and female predicates and then test the entire thing using Prolog.
2. Write a Prolog relation remove(E,L,R) that is true if R is the list which results from removing one instance of E from list L. The relation is false if E isn't a member of L.
What are all of the answers to the following queries?
ask remove(a,[b,a,d,a],R).
ask remove(E,[b,a,d,a],R).
ask remove(E,L,[b,a,d]).
ask remove(p(X),[a,p(a),p(p(a)),p(p(p(a)))],R).
3. Write a Prolog relation subsequence(L1,L2) that is true if list L1 contains a subset of the elements of L2 in the same order.
How many different proofs are there for each of the following queries?
ask subsequence([a,d],[b,a,d,a]).
ask subsequence([b,a],[b,a,d,a]).
ask subsequence([X,Y],[b,a,d,a]).
ask subsequence(S,[b,a,d,a]).
Explain why there are that many.
4. Write a Prolog relation that returns a list containing the union of the elements of two given lists.
5. Write another relation (anything you want) that does something not performed above. Explain what your relation does.
