Problem solving with Prolog

The findall predicate.

How would we compute all the subsets of a set (represented as a list)?

The fact establishes that the empty set (i.e., the empty list) is a subset. The first rule that a subset contains the first element of the set and possibly some of the other elements. The third rule that ignoring one element of a set (the head of the list), a subset will be contained in the set of the remaining elements.

Thus for example

in which the first unifier is built in a refutation based on two resolutions with the rule subSet([H|T], [H|R]) :- subSet(T, R). and one with the fact subSet([], []). ; the second unifier based on one resolution with the first rule, one with the second rule ( subSet([H|T], [H|R]) :- subSet(T, R). ), and one with the fact; the third unifier based on one resolution with second rule, one with the first rule, and one with the fact; and, finally, the last unifier is based on two resolutions with the second rule and one with the fact.

How would we compute the power set of a set? The power set of a set is the set of all of its subsets. So for this we would need to collect all the unifiers for the second argument of subSet that make it hold. Luckily, Prolog has a useful pre-defined predicate providing this, findall .

The predicate takes three arguments:

The interpretation of findall is such that all the instantiations of T , which would be generated in making P hold, are added to a list and unified with R .

We can thus write a power set predicate as

since for each possible way in which subSet(S, SS) can hold the respective instantiation for SS will be accumulated in a list, which will be unifier with P when all possibilities are exhausted.

All the permutations of a list

Similarly to the power set, we can compute all the permutations of a list by combining findall with perm :

The eight-queens problem

The eight-queens problem is a classic puzzle: how to place eight queens in an 8x8 chees board such that no two queens threaten each other? Using Prolog we can solve this problem not bothering how to actually solve them: it suffices to encode in Prolog the restrictions for a possible solution and let its unification + resolution machinery compute the solution for us.

From the chess rules, a solution for the eight-queens problem must be such no two queens share the same row, column or diagonal.

Representing a configuration of the board (and the column test)

A configuration of the board is where the eight queens are positioned in it. We thus need eight positions to represent a configuration. Since queens cannot share columns, there must be one queen in each column. We can start from that when representing possible legal configurations.

Using a list of integers, from 1 to 8, with each position in a list representing in which row the queen of the respective column is, we can represent a configuration.

For example, [4,2,7,3,6,8,5,1] means that the queen in the first column is in row 4, the queen in the second column in the row 2 and so on.

The row test

Queens cannot share rows. Since we represent the row a queen is on in a configuration with a number from 1 to 8, it must be the case that there are no repetitions in a configuration and that all from 1 to 8 occur. This is to say that a configuration must be a permutation of of the numbers from 1 to 8.

The diagonal test

A queen placed at column X and row Y occupies two diagonals: one from bottom-left to top-right and one from top-left to bottom-right. We name these diagonals: the former is the diagonal C = X - Y and the latter is the diagonal D = X + Y .

So we can define the diagonal test predicate as follows:

which is such that given a configuration Q the predicate test(Q, 1, [], []). holds, if, for each queen, its diagonals have not been previously occupied. The predicate \+ is true if and only if its argument cannot be shown to hold.

Generating all possible configurations

All possible configurations of the board amount to all possible permutations of a list. Thus we can build a solution to the eight queens problem by:

How many solutions exist for the eight-queens problem?

How do we find all solutions? Or how de we count all solutions? We can rely again on findall :

P-99: ninety-nine prolog problems, [email protected] or [email protected], working with prolog lists.

A list is either empty or it is composed of a first element (head) and a tail, which is a list itself. In Prolog we represent the empty list by the atom [] and a non-empty list by a term [H|T] where H denotes the head and T denotes the tail.

You can check your predicates using these example trees. They are given as test cases in p54.pl .

Integrity of Scholarship

University rules on integrity of scholarship will be strictly enforced. By completing this assignment, you implicitly agree to abide by the UCSD Policy on Integrity of Scholarship described beginning on page 62 of the Academic Regulations section ( PDF ) of the 2002-2003 General Catalog, in particular, "all academic work will be done by the student to whom it is assigned, without unauthorized aid of any kind."

You are expected to do your own work on this assignment; there are no group projects in this course. You may (and are encouraged to) engage in general discussions with your classmates regarding the assignment, but specific details of a solution, including the solution itself, must always be your own work. Incidents which violate the University's rules on integrity of scholarship will be taken seriously.

In addition to receiving a zero (0) on the assignment, students may also face other penalties, up to and including, expulsion from the University. Should you have any doubt about the moral and/or ethical implications of an activity associated with the completion of this assignment, please see the instructors.

Code Documentation and General Requirements

Code for all programming assignments should be well documented . A working program with no comments will receive only partial credit . Documentation entails writing a description of each predicate as well as comments throughout the code to explain the program logic. Comments in Prolog begin with a percent sign (%) and are terminated by a newline/carriage return. It is understood that some of the exercises in this programming assignment require extremely little code and will not require extensive comments. Nevertheless, comments describing recursions and helper predicates are required.

While few programming assignments pretend to mimic the "real" world, they may, nevertheless, contain some of the ambiguity that exists outside the classroom. If, for example, an assignment is amenable to differing interpretations, such that more than one algorithm may implement a correct solution to the assignment, it is incumbent upon the programmer to document not only the functionality of the algorithm (and more broadly his/her interpretation of the program requirements), but to articulate clearly the reasoning behind a particular choice of solution.

Assignment Overview

The overall objective of this assignment is for you to gain some hands-on experience with problem solving using Prolog, using simple facts and rules, recursion, and database handling capabilities of the language.

The instructions for submission of your assignment may be found at the bottom of this page of this document. It is a good idea to start this assignment early; Prolog programming, while not inherently difficult, often seem somewhat foreign at first, particularly when it comes to recursion and list manipulation.

So as not to make the code overly long, it is not required that you deal with user errors: you can assume that the user always types valid commands (e.g., if a predicate is supposed to take an atom as argument, you do not have to check whether the argument is instead a list and throw an error). Note that the Prolog interpreter catches a good number of user errors anyway.

Problem #1 - Uncles and Half-Sisters (40 points)

parent(john,ann). parent(jim,john). parent(jim,keith). parent(mary,ann). parent(mary,sylvia). parent(brian,sylvia). male(keith). male(jim). female(sylvia). female(ann). male(brian).

Question #1: Uncle (20 points)

Write a Prolog predicate uncle(X,Y) that is true if X is Y 's uncle. Note that we are not considering uncles "by marriage", meaning that for X to be Y 's uncle the two must be related by blood. For instance (user input is in red ):

?- uncle(keith,ann). Yes ?- uncle(ann,mary). No ?- uncle(keith,X). X = ann ; No ?- uncle(john,ann). No ?- uncle(X,Y). X = keith Y = ann ; No

Problem #2 - Lists (160 points)

Question #1: Sublist (20 points)

Write a Prolog predicate sublist(X,Y) that is true if list X is a sublist of list Y . A sublist is defined as the original list, in the same order , but in which some elements may have been removed. For instance (user input is in red ):

?- sublist([a,b],[a,e,b,d,s,e]). Yes ?- sublist([a,b],[a,e,e,f]). No ?- sublist([a,b],[b,a]). No ?- sublist([],[a,e,e,f]). Yes ?- sublist([a],[]). No ?- sublist(X,[a,b,c]). X = [] ; X = [a] ; X = [a, b] ; X = [a, b, c] ; X = [a, c] ; X = [b] ; X = [b, c] ; X = [c] ; No

Question #2: Detecting Duplicates (30 points)

Write a Prolog predicate has_duplicates(X) that is true if list X contains duplicated elements (that is at least 2 copies of an element). For instance (user input is in red ):

?- has_duplicates([a,e,b,d,s,e]). Yes ?- has_duplicates([a,b,d,s,e]). No ?- has_duplicates([]). No

Question #3: Detecting Triplicates (40 points)

Write a Prolog predicate has_triplicate(X) that is true if list X contains triplicated elements (that is at least 3 copies of an element). For instance (user input is in red ):

?- has_triplicates([a,e,e,d,s,e]). Yes ?- has_triplicates([a,a,b,e,b,s,s,e]). No ?- has_triplicates([]). No

Question #4: Remove the third element (10 points)

Write a Prolog predicate remove_third(X,Y) that is true if list Y is just list X with its third element removed. If X has no third element, then the predicate should fail. For instance (user input is in red ):

?- remove_third([a,e,e,d,s,e],L). L = [a,e,d,s,e] ; No ?- remove_third([a,b],L). No

Question #5: Remove the nth element (30 points)

Write a Prolog predicate remove_nth(N,X,Y) that is true if list Y is just list X with its Nth element removed. If X does not have an Nth element then the predicate should fail. You can assume that N is strictly greater than 0. For instance (user input is in red ):

?- remove_nth(4,[a,e,e,d,s,e],L). L = [a,e,e,s,e] ; No ?- remove_nth(6,[a,b],L). No

Question #6: Remove every other element (30 points)

Write a Prolog predicate remove_every_other(X,Y) that is true if list Y is just list X with every other element removed (the two lists should have the same first element). For instance (user input is in red ):

?- remove_every_other([a,e,e,d,s,e],L). L = [a,e,s] ; No ?- remove_every_other([a,e,e,d,s],L). L = [a,e,s] ; No ?- remove_every_other([],L). L = [] ; No

Problem #3 - A Prolog Database (130 points)

store(best_smoothies, [alan,john,mary], [ smoothie(berry, [orange, blueberry, strawberry], 2), smoothie(tropical, [orange, banana, mango, guava], 3), smoothie(blue, [banana, blueberry], 3) ]). store(all_smoothies, [keith,mary], [ smoothie(pinacolada, [orange, pineapple, coconut], 2), smoothie(green, [orange, banana, kiwi], 5), smoothie(purple, [orange, blueberry, strawberry], 2), smoothie(smooth, [orange, banana, mango],1) ]). store(smoothies_galore, [heath,john,michelle], [ smoothie(combo1, [strawberry, orange, banana], 2), smoothie(combo2, [banana, orange], 5), smoothie(combo3, [orange, peach, banana], 2), smoothie(combo4, [guava, mango, papaya, orange],1), smoothie(combo5, [grapefruit, banana, pear],1) ]).

The first store has three employees and sells three different smoothies, the second store has two employees and sells four different smoothies, and the third store has three employees and sells five different smoothies. You can assume that there are no duplicates ( pineapple is not listed twice in any ingredient list, mary is not listed twice in any employee list, the same smoothie specification is not listed twice in any store menu, etc.). Given a database of smoothie store facts, the questions below have you write predicates that implement queries to the database.

Question #1: Sells More than Four Smoothies (10 points)

?- more_than_four(best_smoothies). No ?- more_than_four(X). X = all_smoothies ; X = smoothies_galore ; No

Question #2: exists (20 points)

?- exists(combo1). Yes ?- exists(slimy). No ?- exists(X). X = berry ; X = tropical <enter> Yes

Question #3: Employee to Smoothie Ratio (20 points)

?- ratio(all_smoothies,R). R = 0.5 ; No ?- ratio(Store,R). Store = best_smoothies R = 1 ; Store = all_smoothies R = 0.5 ; Store = smoothies_galore R = 0.6 ; No

Question #4: Average Smoothie Price (25 points)

?- average(best_smoothies,A). A = 2.66667 ; No

Question #5: Smoothies in Store (30 points)

?- smoothies_in_store(all_smoothies,L). L = [pinacolada, green, purple, smooth] ; No ?- smoothies_in_store(Store,L). Store = best_smoothies L = [berry, tropical, blue] ; Store = all_smoothies L = [pinacolada, green, purple, smooth] ; Store = smoothies_galore L = [combo1, combo2, combo3, combo4, combo5] ; No

Question #6: Fruit in All Smoothies (25 points)

?- fruit_in_all_smoothies(Store,orange). Store = all_smoothies ; No

Problem #4 - A More Complex query (70 points) [EXTRA CREDIT]

?- find_smoothies(L,[banana,orange],[blueberry,mango]). L = [all_smoothies, green, smoothies_galore, combo1, smoothies_galore, combo2, smoothies_galore, combo3] ; No

The smoothie "green" sold in the "all_smoothies" store, and the smoothies "combo1" and "combo2" sold in the "smoothies_galore" store, are the only smoothies with both banana and orange and without any blueberries or mango, hence the result to the above query.

?- find_smoothies(L,[orange,banana],[mango,blueberry]). L = [all_smoothies, green, smoothies_galore, combo1, smoothies_galore, combo2, smoothies_galore, combo3] ; No

?- find_smoothies(L,[mango],[]). L = [best_smoothies, tropical, all_smoothies, smooth, smoothies_galore, combo4] ; No

?- find_smoothies(L,[],[banana]). L = [best_smoothies, berry, all_smoothies, pinacolada, all_smoothies, purple, smoothies_galore, combo4] ; No

Submission Guidelines/Instructions

Your functions/programs must compile and/or run on a UNIX ACS machine, as this is where the verification of your solutions will occur. While you may develop your code on any system, ensure that your code runs as expected on an ACS machine prior to submission. Code which does not compile and/or produce the desired results on the testing machine will receive little or no credit. You should test your code in the directories from which the tar file (see below) will be created, as this will approximate the environment used for grading the assignment.

Creating the tar file for submission

Your answers to this assignment will be stored in separate files under a directory called <username>_cse130_pa2/ . For instance, I would create a directory caller casanova_cse130_pa2 . The directory hierarchy should appear as follows: <username>_cse130_pa2/ problem1.prolog problem2.prolog problem3.prolog problem4.prolog For example, as indicated above, in the <username>_cse130_pa2 directory, you should have a file named problem1.prolog , which will contain the documented Prolog source code to implement the functions specified in Problem #1 of this assignment, a file named problem2.prolog , which will contain the documented Prolog source code to implement the functions specified in Problem #2, and so on. Assuming the directory hierarchy above, populated with the problem solutions as described, you should create a tar file called <username>_cse130_pa2.tar by running the tar command in the directory where the <username>_cse130_pa2 directory resides. If you don't know anything about tar , I strongly suggest you learn about it as it is very useful (the man page is rather lengthy, but you can find a more gentle introduction there ). For example, in the directory containing the above directory, I would run the command tar -cvf casanova_cse130_pa2.tar casanova_cse130_pa2

which would create the desired tar file (in this case, named casanova_cse130_pa2.tar ) from the directory named casanova_cse130_pa2 .

Submitting the program via the turnin program

Once you've created the tar file containing all of your answers to the assignment questions, you will use the turnin program to submit this file for grading. Using the turnin program is straightforward. Assuming I am in the directory where I've created the casanova_cse130_pa2.tar file, I would simply run the turnin command as follows: turnin -c cs130s -p pa2 casanova_cse130_pa2.tar

The turnin program will provide you with a confirmation of the submission process; make sure that the size of the file indicated by turnin matches the size of your tar file. See the ACS web page on turnin for more information on the operation of the program.
