How did everyone find it? I forgot a few things, but I'm hoping for a low/mid A. Thought it was a pretty standard paper, but I was disappointed to not see an algorithm question though! :tongue:
Was J = 15 for Dijkstra's? G = 13?

i got something like this. i think ive labled the questions wrong but do peoples answers look something like this?
2a. 9
b. 6
c. 45

3a. 26
b. 10<x<14

4a. 189
b. 177
c. 179
d. B

5a. x<4 x>>3
b. x=3

6. 14 edges

7a. 36
b. 62
c.62 and 74
d. optimal is 62 as upper = lower

8a. x=21 y=10
b. profit =520


for 3b I think I got x>>10 or something. What even was Q3 I can't remember lol

Same for last question y=8 and x=24 so profit was 520£
That was too easy wow

How many will I drop if I left the profit thing as 64/3 and 32/3 instead of integers????

For Q8b, doesn't x=21 and y=10 give P=£515? I'm sure the equation was P=15x+20y

I got profit 520? I used x=24 and y=8.

My lower = upper bound, 62 (the other upper bound I had was 67).

Prim's matrix was 36.

For Chinese postman I had 22, 32 and 42.


Yeah i got 24 and 8

it sure does... i typod it. in the exam i put £515

i dont know how people are getting x=24 y=8 its not the same objective line.

objective line was y=-(3/4)x
