I am in need of free software that will work with polynomials over the Tropical semiring. I was unable to find anything suitable, so I thought I would take a stab at implementing them in sage. I have just barely found sage though, so I don't yet understand it entirely. This list seemed very friendly so I thought I would ask a few questions:
1. Is this already implemented under a different name (it's also called min-plus algebra), or someplace that I overlooked? 2. Is it reasonable to implement in sage? In particular one thing that I think may be difficult is that the polynomial 'x+3' is really '0*x+3' since 0 is the multiplicative identity (infinity is the additive identity). 3. Where is the best place to go to find out how to develop a sage package etc. Also good tutorials for python would be appreciated, since I have never done any python development. I do have experience in a variety of other languages. 4. Would this be better to implement in something like GAP (so that GAP users can take advantage of it as well) and then access it through sage?
