I can second the experience that learning things in order to solve a problem works great. I struggle when I just have to sit down and lear something from scratch, without any direct application to the knowledge. But as soon I can project concepts and theories onto a problem I want to solve, I have no issue learning new things.

Currently I learn a lot about relational algebra and algebraic semirings, because they are part of the theory behind constraint programming, which I use in a current project.

Out of curiosity, how would you say that relational algebra and algebraic semirings help you with constraint programming? While that can indeed be useful in some cases when doing research in constraint programming, I am curious how it helps you?

Background: I'm a researcher in constraint programming and sometimes user of it in work-related projects.

Not directly with constraint programming itself. And also, I'm not doing a deep dive on these topics. But having an ideal of what is happening under the hood makes gives me more confidence in working with a tool and reasoning about choices.

Interesting. I don't think that would be my first choices of study.

If you want to know more about how constraint programming works under the hood, I can recommend the coursera course Solving algorithms for Discrete Optimization, in particular weeks 1 and 2 for constraint programming. https://www.coursera.org/learn/solving-algorithms-discrete-o...
