CodeJudge We use CodeJudge for testing code and correcting the implementation part of the mandatory exercise. Access CodeJudge at XXX.
Gradescope We use Gradescope for correcting the written part of the mandatory exercise and the final exam. The system significantly improves consistency and quality in grading. Please sign up for Gradescope as follows:
4PGYJ4, your full name, your
@student.dtu.dkemail, and your student-id (of the form
s123456). Please follow these instructions precisely so that we can correctly identify you.
The weekplan is preliminary and may be updated during the course.

The course has a single mandatory exercise. The mandatory exercise is done in small groups.
Collaboration policy The mandatory exercise is subject to the following collaboration policy. The exercise should be done in groups of 2 or 1 (i.e., in pairs or individually). It is not allowed to collaborate with other groups on the exercises, except for discussing the text of the exercise with teachers and fellow students enrolled on the course in the same semester. Under no circumstances is it allowed to exchange, hand-over or in any other way communicate solutions or parts of solutions to the exercises to other groups. It is not allowed to use solutions from previous years, solutions from similar courses, or solutions found on the internet or elsewhere.
What programming and mathematics requirements do I need for the course? In general, you need an introductory course in programming and mathematics. We use basic programming extensively to implement algorithms and discrete mathematics to analyse algorithms. See the materials on this page to clarify how this applies to your current competencies in programming and mathematics.
What is the language of the course? The official language of the course is English. Hence the spoken language in lectures and the exam is in English. There are Danish exercise classes and your are free to hand in the mandatory exercise and the exam in Danish.
What is the programming language used in the course? You can use most standard imperative programming languages (including Python, Java, C, and C++). The language must be supported by CodeJudge.
I need to quickly refresh my programming skills. What do you recommend? We suggest the book "Introduction to Programming in Java", Sedgewick and Wayne. The book is compact, concise, and focused on the core technical aspects of programming. The books covers essentially all relevant material for the course in chapter 1, which is freely available at the homepage for the book.
Which supplementary books/materials do you recommend? We suggest the following:
When and where is the exam? Please see the DTU exam schedule.
