Comment (by darij):
Hi Travis,
I'm going to review this (at least mathematically) in the next time, but
one question first: does TropicalSemiring(R) really work only for rings R
as the doc says, or also for ordered additive groups R (as it should
imho)? I'm just not seeing where in the code it uses multiplication (and I
hope it does not).
(Also I see a typo "parituclar".)
Thanks a lot for the code; it's coming very handy for what I'm doing these
days!
Best regards,
Darij
