I had a question on that topic placed in Electrical Engineering, and it was closed because "off-topic". It took a while but I found information on the scope of that community, and I understand why the question was closed there. But what is the right community to ask it?
I posted this question here because of the first answer in What should I do if I cannot find the right community for my question?.
However, instead of asking a meta-community, I would prefer to find the solution of my problem on my own, i.e. through a proper search across all communities, and then see where the hits are clustered.
