If you find any errors in the slides or handout, please send an email to tms41 at cam.ac.uk or approach me after the lecture.
Distributed during the first lecture. It will be to your advantage to bring your handout to every lecture, together with a notebook with non-detachable pages and a few coloured pens. Further printed copies of the handout are available from the student administration office in the William Gates Building. An electronic copy is also available.
Please use the online Otter system, which is still somewhat experimental, and help us make it work for you by providing constructive feedback on how it could be improved. We are aware that there may be teething problems but please support us. To help you in the meantime, here are last year's exercise sheets for Algorithms I and Algorithms II, covering similar ground to the first and second half of the course respectively. New exercises and exams will only be added to Otter from now on.
Past exam questions for Algorithms I, Algorithms II, Data Structures and Algorithms (old) and Algorithms (old) may be of interest. If you want to own this material rather than just memorize it, attempt the questions as seriously as if you were taking the exam yourself and do not open the solution notes until after having irrevocably committed (no more changes) to your own solution. The best students already understand the wisdom of this advice; for the others, yeah, the pressure is high, the temptation is strong, the flesh is weak...
