Assignment 3

Hi Guys,

Any thoughts on Assignment 3?
Difficulty? Which parts of the text book was easy? Which parts of the text book was difficult?

Did you understand all the concepts? etc...

I get the concepts, it's Prolog I'm struggling with Still stuck on question 1, unfortunately. You?

I just finished question 1 last night. I took 2 days off from work to sit with this assignment and honestly I'm struggling to turn a state space into prolog statements.

I have 3 problems:
1 Deciding on the terminal clause.
2 Understanding how prolog will iterate through the list to produce successor states.
3 Keeping track of what states I've covered.

So basically I don't know how to convert what I know about the state space into anything meaningful in Prolog.

I used depthfirst2 for question 1 as appears in the text book (can't remember which page). It is depth first search with iterative deepening. Not sure if I should try the standard depth first search; but with so little time remaining I think I'm going to leave my solution as is and tackle the other questions.

BTW: I copied the legal moves from the solution given for best first search in question 1. I didn't change anything regarding the legal moves.

Before I answer the next question I'm going to try some simple List Iterations with a terminal clause and try and wrap my head around how prolog attempts to find a solution. I think I figured out how to trace what prolog is doing last week and that might be key to understanding how prolog goes about finding a solution.

I really struggled with this assignment - in the end handed it in with only Question 1 solved. Not sure where to go from here - anyone want to form an online study group or something?

Hi Peter,

I also struggled with this assignment. I would be interested in joining an online study group, problem is I don't know if my input will be valuable. Assignment 3 Questions were really out of this world. It was unreasonably difficult to learn what was expected from the text book and further more given our time constraints with work and other assignments it is really difficult. I am considering asking the lecturers for tuition. So maybe if we get a big enough group one of the lecturers will be able to give us a lesson. I'm willing to take a days leave and go to the university during the course of the day.

Well, Mrs Horne recommended the Van Le book, "Techniques of Prolog programming" - I have requested it from the Unisa library. Beyond that, maybe we can chose some problems (similar but not the same as the assignment ones) and throw around some solutions?

That would be great, however, I think we should do this after our assignments are all in because I have AI and Formal Logic due next week.
