Open 2023c

All exercises

Welcome to Open 2023c — PPC open, autumn 2023!

This is a free online course that is open to everyone. Please note that this is not a normal university course, and you will not get study credits by completing this course. Nevertheless, the course content and grading is very similar to the official Aalto University course, so you can directly see how well you would have done in the real course! There is no support available and no human being in the loop, but there is plenty of course material freely available online. Have fun solving problems!

You can try to solve the following exercises. For full points, please submit your solution before the deadline; for partial points you can still try to submit until the course ends. Resubmissions are always safe; you will never lose points if you resubmit something (but if you resubmit after the deadline, you will not get full points that way, either).

“Points” — the points scored by your submissions according to automatic grading, or the amount given by our course staff after manual review.

“Rec.” = recommended path — while you are free to solve any of the exercises in any order, we suggest that you try to solve at least these exercises.

“Rating” — an approximate indication of how much effort is needed for getting full points in each exercise. 1-star problems are easy to solve without too much effort, typically with less than 100 lines of code. 2-star problems may require a careful application of the ideas presented in the course material and plenty of experimentation, and a solution is typically more than 100 lines of code. 3-star problems are small research projects. Please note that in many of the exercises it is often much easier to get some points than full points.
