Computing tropical ranks

The code on this page computes tropical ranks with respect to various tropical varieties. Since it relies on external programs in order to do the actual computational work, you will need to install extra software.

The algorithm for computing the rank of classical secant varieties is implicit in the paper "Tropical secant varieties of linear spaces" by Mike Develin. The construction of deficiency graph is described in "Three notions of tropical rank for symmetric matrices" by Dustin Cartwright and Melody Chan.
