**** I didnt see the last bit where you calculate 5550 How many marks was it?
Don't think it would be more than 2 or 3 (only simple calculations), probably haven't lost many marks if you missed it

2 marks
3. what did you guys get for the output for each month?
I got 3,3,5,5,3
4. Questions 1,2,3,4 and 5 were brilliant. Not so much questions 6 and 7 but I couldn't do dynamic programming from day 1 so not too bothered. Only need BB in maths and further maths so asking as I get a C ish should be fine. If I got all 1-5 correct and 2 marks on q6 do you think I can get a C overall??

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

- 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?
Wasn't the game theory 0=/=4? Not -4?

7. For the optimal length in question 1, the boundaries were 113 and 158 right?
8. Never mind it was -4 i just remembered wrong.

Yep

Oh wait yeah lol

You got 113 and 149 as well?
14. was the last question just minimising right???
15. (Original post by anonymous2410)

I forget whether I put 149 in the inequality, but I definitely got 113 and 149 in the previous parts, and 149 is definitely a better upper bound than 158.
16. For the question on game theory when it asked you to formulate it as a linear programming problem (the question before you had to put it in the simplex) did it say write your answer as inequalities or equalities??
17. What were theta values in the stepping stone question?
18. (Original post by Historygcse)
What were theta values in the stepping stone question?
3 and 11?
19. (Original post by anonymous2410)
3 and 11?
I got that. Was the final solution optimal?
20. What did you guys get for the profit of the last question? i got 900 something
