Felt pretty good about my answers, discuss yours too:

1.

a. 58 hours
b. CGIKL
C. Float time = 2
d. 60 hours worker 1: critical path 2: everything else

2. 61

3. Define zero-sum game

Monica plays C Vladimir plays ?

B dominates C

play A with p = 0.6, C with 0.4

Play D with 0.9, E 0.1 F 0

4. 3 as 8 < 20 and 15

Max P = 36, x = 6, y = 0, z = 6, s = 8?, t = 0, u = 0

5

DBCA

6.

X = 45?

Max flow = 32

Hope these are all right.
wasn't B dominated by C?
2. I got 30 for the last question, and my diagram showing it was correct, i missed out on one flow. How many did i lose would you say?
3. I got 63 for the minimum time with two workers. My two workers worked 55 then 1 worked an extra 8 on the last letter which I can't remember
4. Pretty good exam! What are predictions for 90 ums

67/75
6. Will update what i can remember

Yes C dominated B. My mistake
7. I got 62 hours for the last part of Q1? I hate those resource leveling questions though so it mightn't be right ahha

Overall I thought the paper was nice
8. I got 63 on 1d for what it's worth
9. How may solutions were there for question 2? You needed to give all possible allocations..

Definitely at least 4 that give 61, but I don't think there was any more than 4.

Finally, somebody other than me who got 63; I hope we're both right
