1. good luck everyone
2. (Original post by DORI)
thats what i thought but apparently its not like that......
he would rather play 4 than play 2
I meant why would he play 2 when he can play 4. If you are looking from the defensive players prespective, take the negative of all values.
3. 1650 5200.........??
4. Can someone please do me a favour and tell me the exact thing they got for the last dynammic programming question

5225 i think?
6. (Original post by YZ31618)
5225 i think?
I got 1700 for part a and 5550 for part b
7. i got 1700 and last part 5550. Not sure if correct tho
8. i got 1700 and 5550 for dynamic programming.
9. Made a mistake somewhere in my tables and got 2000 for last q. Got the programming part right tho. Wonder how harsh the markscheme will be. Maybe 2 accuracy mark, and then 1 accuracy mark in the next part.

I dont want the answer i want the full working out lol
11. - Simplex not optimal because you had -5s?
- Hungarian 248
- Flow one you got a flow Max flow of 62 and proved it with min cut, max flow theorem?
- Gametheory 0 does not equal -4 therefore it stable?
- North west corner method dummy with value 14 so they both are 99?

Can you remember how you managed to increase the flow by three units? I couldnt find a route to increase any more than 2...
15. I think i had a brain fart on the augmented flow diagram. Couldn't find a route from S to T that allowed an extra 3 units to flow??

therefore it not stable

I agree
19. **** I didnt see the last bit where you calculate 5550 How many marks was it?

You needed to use backflow which would reduce the arc by 3 that seemed like it could only be increased by 2.
