Thank you - would "activities xxx commencing at day 12" be sufficient for the marks, do you think?

I put that 5 activities must be happening at time 12.5 hence the lower bound of workers is 5

Awesome dude - sounds like there's a lot of similarities, if you drop me PM later or a visitor message or something we can talk some more later about it all! I feel like we're going slightly off topic here and probably annoying some others that's all!

And no but I have considered STEP 1

I thought that I remembered getting something like that, too... I'm sure that I got either 126m or 136m for it...
Pretty sure that my pairings were 75, 85 and 125. Repeating the arcs with 75 and the total length being 382+75=459

What thread do you call this?
I said that on day 12, 5 activities must be happening so the lower bound is 5
however some people on here are saying that you had to say "on day 12.5"

does it make a difference? will I lose marks?
Original post by 4nonymous
For the dikstra. I got 49 for part a but everyone seems to have got 48. How many marks would I lose. And does anyone remember the route for part a.


I got 48 for part a and 49 for part b. How many marks you lose depends on your working values, I think you'd lose 2 or 3 marks at most.
for the last one I used 2y + x will I still get carry through marks for rest of question
