D1 (Decision 1) 17 May 2013 Official Thread

I did that without testing regions lol I literally did half LP question within 2 minutes.... I had so much trouble plotting Objective Function as well first i did 100x + 300x = 900 ... too small rubbed it out then same with 100x + 300x = 1800
then finally 100x + 300x = 3600 ... my objective line was still too small though
I agree with the bin packing I can't remember if I got it right though, but definitely got 4 bins for both




Yup let's not worry too much At least we all know we've improved ! Just hoping for very low grade boundaries now !!!


Any of you guys doing C2 next week ???

I think a lot of people has a prob with timing in that paper esp considering the last 2 Qs were very long & worth a lot of marks so just like posthumus stated I hope Grade boundaries are low because I would say that there were some tricky bits to some of the questions plus what happened to the easier contraints/inequalities we used to get? Like y>3 etc?

Yes hope so!! When is your next exam.

Yep, please, please let the GB be low, please No I'm not doing C2, got C3 & C4 left now
