| * Matthias Walter: With [[http://github.com/xammy/unimodularity-test/wiki/Polymake-Extension|this extension]] you can test an integer matrix for total unimodularity. If the answer is "no", it can return the row/column indices of a submatrix with |det| >= 2. It can also test for the related properties (strong) unimodularity, (strong) k-modularity and the Dantzig property. See [[http://www.math.uni-magdeburg.de/~walter/TUtest/|here]] for more information on implementation and theory. | * Matthias Walter: With [[http://github.com/xammy/unimodularity-test/wiki/Polymake-Extension|this extension]] you can test an integer matrix for total unimodularity.
