I found an interesting article (to me at least) that I want to play around
with, but am not fluent in Greek (Pure mathematical functions) .
the algorithm itself starts around page 4 (5 is graphs), 6 has its 'pseudo code',
which is all Math.
I don't understand what
||v_t|| or ||vt_best|| (the double pipes, or how to evaluate them)
in this context mean.
Any nudge in the right direction is super appreciated.
