I understand that what I say might sound a little bit too "dry".
It's just because I start at the bottom (at the low level, simple components)
and try to go in the ascending direction (high level, complex entities).
I assume as little as possible and try to see if it is enough to make a step in
the ascending direction. I don't add a new concept until it is absolutely
necessary.
I do that also with computer chess. I have expressed several times this idea,
and rejected a number of common assumptions, on the ground that these
assumptions were not necessary and were just there to add complexity and
confusion to an otherwise rather simple model.
One might disagree, but that's just the way I look at a new problem, generally.
