K. H. Kim, F. W. Roush
We show that determining Kapranov rank of tropical matrices is not only NP-hard over any infinite field but also if solving Diophantine equations over the rational numbers is undec…

Factorization of polynomials in one variable over the tropical semiring
Ki Hang Kim, Fred W. Roush
We show factorization of polynomials in one variable over the tropical semiring is in general NP-complete, either if all coefficients are finite, or if all are either 0 or infinity…
