- State Space - Damn puzzles in exams, but we knew it would happen. Didn't include the boat, which is why I couldn't get it.
- CSP - Assignment questions which I was truly amazed by, so I knew it from the beginning of the year
- Resolution Refutation - Not too bad, a few statements I didn't think needed to be there, so hopefully I'm right there
- Search - Woop woop :D
- Alpha-Beta - 1x Beta cut, 2x Alpha cuts as far as I could tell
- CNF - Wasn't too bad
- Decision Trees - Pretty straightforward

I think I may pass, which would be great considering the work put into this and interest in it in general.]]>

Looking at the past exam with Question 1 - I understand the state space and how to portray it (like in 1.2 the first answer).

I can't seem to wrap my brain around the second notation however:

Quote

f3 : if 3< T then (3, F)

f5 : if 5< F then (T, 5)

e3 : if 0> T then (0, F)

e5 : if 0> F then (T, 0)

p3,5: if (5-F)<=T then (T-(5-F),5) else (0,T+F)

p5,3: if (3-T)<=F then (3,F-(3-T)) else (T+F,0)

Anyone got some clarity, no matter how I convert it to english, I end up sounding wrong.]]>

I think I'm being really doff :(]]>

I can't see how they decide which is an alpha and which is a beta.

To me all B, C and D should all be beta values, but they are not.

Same on the next level. All values should be alpha values but they are not.

Please, help, someone!!!!!]]>

It asks to use resolution to determine what James does when he needs money.

So how do we go about this?

Do we assume what he does and state a goal?]]>

which page(s) in chapter 7 covers this ?]]>

I am quite concerned in regards to the "No Calculator" rule in the exam coming up. Looking at the past paper, the table given at the end gives absolutely no indication of the entropy, or the other log functions for that matter, only the information gain.

Do we just need to work out the logs in our heads? Anyone got an idea?

Cheers,

Kyle]]>

Please could someone remind me of how to do it.

Thanks :)]]>

Do any kind souls have any old exam papers (and answers) available to assist in studying??

I have the Exam Guide tutorial letter for 2009 and 2010 (which are identical) but anything more would be greatly appreciated.

Thanks in advance.

I thought the types of calculations in chapter 18 (pg 659,660) requires one.]]>

Has anyone managed to get all of the paths to yes and no decisions?]]>

Busy with this assignment, and am done with most of it, but just have two questions:

Questions 5 - Did I miss something, or what does the symbol in the middle of the sentence mean?

Question 8a - I just do not know what they are asking here. "The root node must be the

Thanks in advance.]]>

(it's the who owns the zebra question)]]>

I have drawn the state space, no problems. My problem comes in where is says that a value of 1 is assigned to a leaf node if MIN wins, and 0 is otherwise. Maybe I am missing something, but shouldn't it be 0 if MIN wins?

MIN's objective is to go down the route of the minimum value - but if we assign a 0 to MIN not winning, surely MIN will always try to "not win", by trying to reach a leaf node of value 0?

Hope my explanation makes sense, and any insight would be appreciated.]]>

Just wanting to make sure before I go off on this mission - the complete game tree for this questions is going to pretty damn large, right?

I have started it, and very quickly there are lots of nodes (I have excluded the "symmetrical nodes" ). Its not very difficult, just lots of keep track of - and before I carry on expanding the tree, I want to make sure I am on the right track.

Everyone else experiencing the same thing?

1 2 3 4 5 6 7 8

Lets say the initial state is

6 1 4 2 3 5 8 7

The problem is solved by determining the path (i.e. set of directions) the blank is moved, in the case if I move it up I have to displace at least the 5, but its also possible to displace 5 and 4 depending on how you define what happens to UP (there are multiple displacements possible - I have listed 4)

6 1 4 6 4 5 6 1 4 1 4 5 2 5 2 1 3 5 6 3 8 3 7 8 3 7 2 8 7 2 8 7

So my question then: For this type of problem, how is the effect of UP defined? as there can be multple definitions, if you stick to 1 then you can have unsolvable puzzles...]]>

i need question 6 for assignment 2 ie exercise 4.5 page 134. i'm using 3rd edition so the exercises do no correspond with 2nd ed.

just write the question, don't worry about the answer,lol]]>

My flight back home has been cancelled and I'm stuck without my textbooks. I'm stuck in South Africa while being based in London. I know that the next assignment for this module is not due for a while but I'm busy making emergency plans to get it done.

I do have a pdf copy of the textbook but I'm not sure if the page numbers match up correctly so I was hoping that someone could write out the first two questions for me so that I can confirm that the pages match up ok.

Any help would be greatly appreciated.

Kind regards,

Rachel]]>
