Grading (50%): Homework Projects

• Project difficulty depends on the actual topics
• (50%) You can decide to do 5 out of 7 given projects (5x10%), or
• feel free to finish them all (no bonus, but learn more)
• Project will be released as homework after each session
• Coding skeleton will be provided, most likely 100~1000 lines of code
• Solutions will be discussed in a subsequent sessions (hence submission period is 1 week)

PC (Blender) Support

• We may need to use PCs with dedicated GPUs in some of the projects.
• If you need support for a PC, send an email titled by "[GP] PC room request" with your name and matriculation number to me (changkun.ou@ifi.lmu.de) using campus address (@campus.lmu.de) before 30.10.2021.
• You will receive the credentials when the room is ready for you, then
• You must make an appointment via email to changkun.ou@medien.ifi.lmu.de before your visit
• Room address: Frauenlobstr. 7a Room 352
• Bookable slots: 10:00-13:00 & 13:00-16:00

Late & Cheat Policy

• Late submission: We don't accept late submission.
• Cheating: You don't.
• Coding projects will surround the re-implementation of well-known GP algorithms, workflows, etc.
• If one sent a pull request, then he/she's the solution will be visible publicly
• We will discuss the solution anyway
• If you found someone plagiarize your submission, ask the person to stop privately; if you can't find consensus together, please talk to me
• If you just want a pass, we do not recommend participation in this course
• Take responsibility for your own study
