ANSWER

1. Select Logic Puzzles: Visit the https://www.printable-puzzles.com/printable-logic-… website and choose two logic puzzles, one labeled as “challenging” and the other as “Very Hard.” You will need the URL of each puzzle to include in your Prolog files.
2. Create Prolog Files:
   • Create two Prolog files named challenging.pl and veryhard.pl.
   • In each Prolog file, define a url/1 fact to store the URL of the respective puzzle. For example:
     prologCopy code

     url('URL_OF_CHALLENGING_PUZZLE').


     Replace 'URL_OF_CHALLENGING_PUZZLE' with the actual URL of the challenging puzzle.

   • Define a solution/1 fact in each file to hardcode the correct solution obtained from the website. For example:
     prologCopy code

     solution(SolutionList).


     Replace SolutionList with the actual solution for the respective puzzle.

   • Implement a solve/1 rule in each file that uses Prolog clauses to solve the puzzle. This rule should derive one, and only one, solution based on the provided clues. You will need to define the predicates and rules required to find the solution.
   • Define a series of clueX/1 rules in each file, where X represents different clues. These rules should be satisfied whenever the solution in T is consistent with clue X. You will need to convert the clues from the puzzle into Prolog clauses and use them in these rules.
   • Include the check rule in each file, as specified. This rule checks whether the solution is valid and if there is only one solution. It should print a message indicating the number of solutions found.
3. Solve the Puzzle: Implement the Prolog rules and clauses to solve the logic puzzle based on the clues provided in the puzzle description.
4. Testing: Run the SWI-Prolog interpreter with the check goal to test your Prolog files for correctness. Make sure there is only one valid solution.

5. Refinement: If necessary, refine your Prolog code until it produces the correct solution and passes the check test.
6. Documentation: Document your Prolog files, including the URL of the puzzles, the clues used, and any other relevant information.
7. Submission: Submit your challenging.pl and veryhard.pl Prolog files along with the documentation as required for your assignment.

Ensure that you have a good understanding of Prolog and logic programming to effectively implement the rules and clauses needed to solve the logic puzzles. Additionally, adapt the provided examples to match the actual puzzle and solution you are working with.
