- The the lecture and exercise on Fridays collided with another course (Computational fluid dynamics). Since it"s rather common to have those two courses at the same time I really think this should be solved until next year.» (75%)
- Other course at the same hours.» (75%)
- Föreläsningarna innehöll för mycket bevis och för lite exempel och tillämpningar. Räkeövningarna var fantastiskt bra för detta men inte avanerade nog för att man skulle kunna klara tentan tyvärr.» (75%)

Goals and goal fulfilment

- Please make it more clear that for grade 4 and 5 there is no point limit, but that the teacher will asses the grade himself. Not many students knew this. » (The goals give some guidance, but could be clearer)

- But the exam questions are of a "tricky" kind, that is they are not testing knowledge and if the course goals are reached but more if you are able to see the "trick" needed to solve the task. Further, the exam questions are WAY harder than the exercises. It"s rather mean to say "we take this briefly cause it"s not so important" at the lecture when going through the proof that was on the exam...» (To some extent)

- The use of powerpoint is not really the best way to go about teaching most of the non-linear program part. For LP"s this is a good method though.» (Small extent)
- -I did not care for the lectures since they were in ppt, but the exercises were good.» (Some extent)

- I was one of a few that showed up for the first scheduled lecture which apparently was canceled with out any of us getting any notice. Also, though the pingpong site was well updated the other website was not as well updated and it took me a while before I understood there was a pingpong site.» (Rather badly)
- Some documents were from previous periods when the course was given and it took quite some time for e.g. the document with recommended excercises to be updated.» (Rather well)
- Hand outs should be posted at least within 24 hours before the exam. » (Rather well)
- I remembered that some old exams with answers contained some mistakes, but when I try to recall which ones, I only recalled mistakes in older exams that apparently weren"t on the new course page. E.g. minus sign in 2009-08-28, problem 3, and a missing minus sign in 2010-01-13 problem 4.» (Very well)

- If one attempts to do all the exercises for bonus points this leads to a large workload.» (High)
- I believe the workload was too high. Not in the sense that the course was unreasonably difficult but between a project in two parts and two computer labs there was little time to work with the recommended excercises which is invaluable for the learning process (at least for me personally).» (Too high)

- TMA947 and DAT036 certainly took its toll but still, really great courses, both of them.» (High)
- Mainly due to the combination of a lot of projects in both of my courses (CFD being the other).» (Too high)
- Depending on other courses» (Too high)

- Too much material in the course» (?)
- I felt we never really digged deep into the methods used for optimization. I would have prefered a little more focus on the algorithms.» (Good)
- I was surprised at first to encounter so much linear programming since the course is called nonlinear optimization at Chalmers. I think introduction to optimization might be the better name.» (Good)
- Has gotten me really interested in optimization.» (Excellent)
- The course is very interesting and brilliantly fun. Somewhat tricky to get an intuitive understanding of stuff at an early stage in the course. Had to do more calculations than usual to understand concepts.» (Excellent)

14. What should definitely be preserved to next year?

- Bonussystems worked very well as a motivation to keep up with the pace of the course. I really appreciated the master classes as an oppurtunity to get a further insight in the area and work with something more advanced in a pretty casual manner.»
- Great lectures and lecturers.»
- The exercise sessions with a brief repetition of wha t was said on earlier lectures were very well. »
- Bonus point system made sure that eventhough high workload in my other course I stayed somewhat in phase.»
- Bonus system for pass/fail level. It"s a good carrot for starting with exercises from week 1.»
- Very good exercises.»
- The main problem of this course is related to TA s of it.This course is very important in my major and i think its too hardfor them to teach or arrange the lecture classes I think if the main teacher was available in lectures then it was useful ,although i appreciate their work, they are not experienced for this course maybe some easier course would be better to teach by TA s. thank to all.»
- - (Happy with the course.)»
- att man kunde få bonuspoäng av att förbereda uppgifter. »

15. What should definitely be changed to next year?

- In my opnion using slides fot the lectures makes it more difficult to follow. If possible i would like this changed. If kept it would be helpful to have the slides available earlier (this year they were sometimes uploaded the same morning when the classes started at 8 am).»
- I did not find computer lab 1 or project part 2 very educating. Either or both could possibly be removed.»
- Not very good with PowerPoint presentations I think.»
- Less powerpoint»
- Bonus system for higher grade. I don"t want to decide at an early stage what grade I"m aiming at, I want to try everything in the course first.»
- More written on the blackboard.»
- More fair examination!»
- -»
- De föreberedda uppgifterna borde inte alltid redovisas, iallafall inte alla. det tog jättelång tid att sitta igenom och gav inte så mycket att se någon annans lösning när man reda gjort uppgiften. Dessutom höll redovisningarna låg kvalite tyvärr.»
- Condense the number of theorems slightly. Also don"t rush through the proofs too fast when presented on lecture. »
