I have some interest in such an implementation, although more as a user of it than an architect/developer. I would encourage you to do it in sage and not GAP.
I can at least commit to help testing any code you work on. There might be some helpful overlap with Anders Jensen's gfan program, which already has a partial interface to sage written. Gfan is capable of some tropical computations, although I am not sure exactly what is externally callable. If you are unfamiliar with gfan, perhaps a good place to start is: http://arxiv.org/abs/math/0507563 Cheers, Marshall Hampton On Jul 2, 10:06 am, [EMAIL PROTECTED] wrote: > I am in need of free software that will work with polynomials over the > Tropical semiring.
