- We haven"t had the exam yet.» ()
- Very nice exercises from almost all the different algorithm categories. And not so extremely difficult as Erland"s in May. :-)» (Yes, definitely)
- Though it was quite hard and I would have needed at least one more hour to even try to solve all the problems on the exam.» (Yes, definitely)
- I find the exam being quite difficult» (Yes, definitely)

- All of the lectures were good. The exercise sessions (both with Erland and with Willard) were very helpful, but in the lectures I would have preferred less focus on the specific problems presented in the book and more on the design principles of each paradigm.» (To some extent)
- I could not attend all courses because of overlapping and because it"s the second time I take the course.» (To some extent)
- i experienced the exercise sessions to be a lot better than the lectures. the lectures sometimes seemed to be off topic, it can be relevant to know what algorithms can be used for and how much money one can earn from solving for example an np-complete algorithm in polynomial time.. but to much time was spent on explaining these things. » (To some extent)
- Solution the the weekly exercises should be available on homepage (at least those solved on blackboard), esp. from the firs part of the course when E.H. was the exercise responsible. E.H while being an excellent lecturer, has terrible hand writing style and is somewhat sloppy with notation. » (Large extent)
- Very good lectures. It"s nice to have a lecturer that makes sure you learn, for a change!» (Great extent)
- Both lecture and exercises (with was more or less also lecture)» (Great extent)
- It was essential» (Great extent)

- It was a good complement to the lectures.» (Some extent)
- The course book although has a good coverage over useful topics, however is very informal hence is big in number of pages and difficult to grasp.» (Some extent)
- Old Complaint: The book doesn"t have solution to the exercises! It means that one can not check if ones solution is correct. Of course if the book had the answers, the teachers would have to come up with their own assignments... » (Large extent)
- the bonusassignments and labs helped alot.» (Large extent)
- the book is a bit fussy at times, especially when it comes to calculating the complexity. if it would be possible to complement how to do that with some handouts or similar the next time the course is given i think that would be great» (Large extent)
- Although I still have problems with the book, it is the best course literature that I"ve had so far.» (Great extent)
- Vero good course book.» (Great extent)
- The course slides are really great. And the book anyway.» (Great extent)

- Some "not mandatory" exercises simply vanished. This means we got 2 less bonus points for the exam than people usually do. Also, information generally has been bad, one lecture disappeared without warning due to Kårdagarna.» (Very badly)
- Please dived the page in to subpages with a mainmenu.» (Very badly)
- Almost no news updates even though there where a lot of changes on the webpage that you had to "discover" by yourself. The weekly problem sets were almost always published to late (which the responsible teacher won"t admit, everyone makes mistakes but owe up and learn from them instead!). The deadlines where not moved, sometimes giving us only half the number of days to complete these tasks. The problem sets took at least one week to long to correct, and some where skipped, giving the students less of a chance (we could not get al the bonus points for the exam) to pass the course than students taking previous runs of the course.» (Very badly)
- better to schedule fewer non compulsary assignments than to cancel them later» (Rather badly)
- A simple notation in news when website has been updated would be nice.» (Rather well)
- quick replies via email which was great. sometimes the info on the course page was contradictory or not up to date. » (Rather well)
- still the old slides in year 2009,can"t find new updated» (Rather well)

- There was some help available for labs via mail, but it was useless since it takes too much time to write down an understandable question» (Very poor)
- Questions over email were answered very quickly, but that does not make up for a complete lack of instructor-led lab sessions (and having to book an appointment or visit the instructor"s office is not at all the same thing).» (Rather poor)
- It would have been nice to have assistants on the labs, like the maths courses are structured.» (Rather poor)
- I would prefer a booked room where we could work on the problem sets and have an oppertunity to ask for guidence. » (Rather poor)
- handlers had trouble understanding the questions» (Rather poor)
- Could always ask your own questions but never listen to others questions (this is both good and bad)» (Rather good)
- good with the consultation hours and possibility to email questions.» (Rather good)

Genomsnitt: 3.57

- It"s a lot more difficult to cooperate with other students when there are no instructor-led lab sessions (which gives most students much less incentive to show up), but I did cooperate somewhat with friends from earlier.» (Rather poorly)
- Since there where no scheduled sessions there where few occations where cooparations would occure.» (Rather poorly)
- Only worked in group with the programming assignment» (Rather well)
- We could have worked more together to solve the problem sets.» (Rather well)
- I like that you can cooperate and discuss the exercises, but that you need to write them up on your own.» (Very well)

- ourse to spare myself the frustration. When the actual corrections of the homework turned out to be less strict than the impression that was given, they became worthwhile. It"s difficult to say anything about the exam before I"ve taken it, but in a course with a pass rate as low as 30% there"s a risk that the exam focuses too much on coming up with clever algorithms in the spur of the moment (six algorithms in four hours) rather than on finding out whether the student has learnt the concepts of the algorithm paradigms and complexity analysis. Two or three "clever" problems can be enough even for an ambitious student to fail, because four hours is not enough time to guarantee coming up with the right "trick" for those problems.» (Poor)
- I was extremely frustrated with the course after the first two weeks when the teacher called us out saying no one had handed in a good solution to the first week"s assignments, despite the fact that the book didn"t give us any detailed information on complexity analysis and the teacher could not direct us to other resources. Saying that we should have learnt that during the Datastructures course just doesn"t cut it, since we obviously weren"t taught about that. I even considered dropping out of the course to spare myself the frustration.

Two or three "clever" problems can be enough even for an ambitious student to fail, because four hours is not enough time to guarantee coming up with the right "trick" for those problems.» (Poor) (den här kommentaren har blivit redigerad i efterhand)
- There should be more information about the exercises. How we should solve them. The leader of the exercises said that out of the 1/3 of the students he had graded. None answered the first problem set correctly. In my opinion this was because we didn"t know how to answer the first problem set from the information we were given before the time to hand it in. (It was not allowed to do the handwaving that was given as solution in the book)» (Adequate)
- lectures weren"t great, the content of the course was great, book was ok, wish there were more exercise sessions» (Adequate)
- good course but handlers and supervision could use improvement» (Adequate)
- Good course, but not entirely my cup of tea.» (Adequate)
- Would have been excellent if not for practical issues» (Good)
- Excellent lectures by D.D. Lecturer presents problems and solutions in consistent and interesting (sometimes funny) way. Some lectures were like watching a good movie. Less time, however should be spent on such trivial topics as: "Google/Yahoo/CompanyX uses algorithms in their programs" Yes, we know that already,) The exercises were challenging but good. E.H. did good job on exercise sessions, interesting and fun to attend. I really liked his reluctance to give away answers too soon! W.R. had a different style, strict, mathematical notation and slower pace, notes published on homepage - very good! » (Good)
- Seems like a "must have"-course for my program. Teaches very good and usable techniques for programming.» (Good)
- This course is a must have.» (Excellent)

12. What should definitely be preserved to next year?

- Pretty much everything besides what I mentioned as bad functioned very well in my opinion. So please keep all that!»
- The lab»
- Problem sets»
- Exercise sessions.»
- good relation exercise session:lecture - 1:2 repeating some things, making things clearer, was very helpful»
- exercise lectures»
- Excercise sessions»
- Exercise sessions»
- problem sets, laborations.»
- Devbatt. Weekly problems. Excercis time»
- The problem sets help to keep up with the course and be prepared for the exam. And they give extra points.»
- (1) Exercise sessions (2) Extra points for solved exercises »
- exercise sessions, generally speaking the content of the course (greedy, divide and conquer, dp, etc) »
- general content of course»
- The lectures where all really good. The problem sets should be kept, but at least one problem each week should be made obligatory. The rest of the problems that week can give additional bonus points. Students learn more this way.»
- Lecture slides are great, task set is a bit time-consuming, but still good. »
- the hand-ins»
- Lecturer. Course book.»

13. What should definitely be changed to next year?

- More info about the exercises before the exercises.»
- You should have people enough too grade all problem sets. The programming assignments could be improved. You don"t learn very much from the first one, and the second one have the answear in the lecture pdfs.»
- Not god to be dependent of the course book to be able to do the hand-in exercises. »
- - Give us one lab session with someone attending in person (not email) - Do not change exam rules in the middle of course - We need more sample exams»
- Instructor-led lab sessions are crucial in such a difficult course, and there must also be a better understanding of what exactly we learnt in the Datatstructures course so that we won"t have to suffer for a lack of communication within the faculty.»
- more money for the course, so that all the problem sets can be corrected in time? but i don"t know if this is possible (if the administration is so flexible)»
- New labs»
- Don"t say one can get X bonus points by doing Y assignments and then break this rule by only handing out Z assignments. »
- I think there sholud be more people correcting the labs and espacially the problem sets, since it took to long to get feed-back on them. I would want more labs, covering diffrent algorithms not only dynamic programming.»
- Willard could handle all exercise session, and the exercise session could be extended to twice a week. There wheren"t enough time to cover all problems.»
- More feedback on weekly problems. Harder lab»
- Tuesday 8-10...»
- »
- The bonusassignments were good but seemed to take up alot of time for the assistants to correct. Maybe they could be shortened somehow so that time and money for the course doesnt become a bottleneck.»
- not removing problemsets, have smaller non credited problems instead.(see additional comments)»
- better handler and better time management by handlers in order to correct submissions in good time.»
- Update the webpage when it changes!!! Give the course a bigger budget to remedy a lot of the bad points. And publish all the problem sets in advance, god damnit! You do not have a good enough reason (to low budget) to not publish them all at one, or at least two weeks in advance.»
- Some other book should be considered. This one is really difficult to read due to it"s informal nature. Consider for instance NP topic introduction in "Introduction to the theory of computation, M.Sipser"»
- The course needs an overhaul. The students need exercise sessions where they can work on their own and ask questions. I think this course would gain a lot from stealing from the Mathematical Modelling course, less lectures, more exercises.»

14. Additional comments

- Thanks for a great course!»
- Good course, good content, good teachers. »
- I didn"t like the fact that we got information about the poor budget planning of the course. If money is an issue, try to hire (cheap) students who have already attended the course as assistent at lab sessions, where we could ask questions about problems sets and laboration.»
- Purchase a clock to Erland and Willard. Both did a good work in exercise sessions!»
- Very good course, albeit difficult. I would recommend it to anyone!»
- sad that some problem sets had to be removed, they were a good way to learn. smaller recommended problems which don"t give points for the exam would maybe be an even better solution. where the solutions could be posted the following week and keeping the consultation hours for questions regarding these. would comply a lot better with GU"s rules of not removing the extra points gained from one exam to another. »
- generally poor performance from handlers. Lab submissions take forever to be corrected. Potential bonus point for exam lost because of poor time and financial estimates from course supervisor and handlers.»
- Good course, but it needs to be more efficient administrative wise, or trim the content of the course, because all the teacher complained about too little resources to manage it all.»
