GenericInitialIdeal -- find the generic initial ideal of a given ideal


GenericInitialIdeal is a package for computing generic initial ideals of ideals in a polynomial ring, that is, the monomial ideal of lead terms after a random change of coordinates. All of these routines are probabilistic: with high probability, they give the correct answer, but it could be the case that the choice of coordinates is too special.



This documentation describes version 0.2 of GenericInitialIdeal.
