I'm not sure I would call it the most challenging class, but it's the one where the most amount of people failed to learn anything. If I had to guess then 90% of the students (or more) ended up not being able to do anything with prolog.
I haven't seen any other class that had such an abysmally low rate of successful learning. I think the only knowledge most people took away from this class is to not use prolog.
This was my only 100% final exam module with no continuous assessment/midterm papers or exams/projects to pick up slack if I failed, so I was nervous going into it. Kinda felt like my whole degree weighed on it. That night before, I just *got it* and it made all the difference in the world. I got how powerful it is, and why to use it.
I haven't used prolog since.
Either people loved the whole different paradigm of logical programming and were really invested or they just didn't want to touch it. There wasn't much in-between.
I think it is great to expose people to different things and I loved it, but I agree for many people that sent prolog straight to their blacklist
> Logical programming (prolog) ... but it's the one where the most amount of people failed to learn anything
I think the implication is that hnthrow098767 would like useful experience at the end of the course.
That being said: 25 years after my prolog course, and 21 years into my career, I wonder if I would take something away from it now.
