After some questions and further evaluation by us, we found that project 1 has a shortcut that we deem unfair: If you happened to find a set of very good seed inputs (and there are plenty of those lists out there), you were basically guaranteed to get the maximum grade, even without having to write a fuzzer. We have therefore split the project 1 evaluation into two parts: One with no seeds, and one with a small set of high-quality seeds provided by us. This will provide a more even playing ground for everybody.

For those of you who previously accepted the assignment: I pushed the changes to your repository directly. Please run git pull. For those of you who have not: You will get the updated instructions directly, once you do accept the assignment.

Refer to the README for the updated instructions and rules. Please re-read the entire README, as multiple things have changed. We are sorry about the inconvenience, particularly to students who have already discovered this and put in some work to find good seeds. If you have any questions regarding the new rules, please ask in the forum.

Written on 18.11.25 by Alexander Liggesmeyer
