14666 Test if a weight function is generic for a given matroid Stefan Stefanf "Reported by darij on http://trac.sagemath.org/sage_trac/ticket/7477 :
Feature suggestion, if not already implemented: a method to test if a given weight function is generic, i. e., has exactly one maximizing basis. Of course, this is easy thanks to the exchange graph, as one only needs to find a maximizing basis and then check that all its exchange neighbours have strictly smaller weight. This function is useful to some Hopf-algebraic constructions." enhancement closed minor sage-7.2 matroid theory fixed matroid, weight function darij yomcat Tara Fife Darij Grinberg N/A 53dc43d1bfff644927da9352c24279bcf897ba9c 53dc43d1bfff644927da9352c24279bcf897ba9c
