Description (last modified by )
short_vector_list_up_to_length uses Pari's qfminim to find short vectors. However, it does not use the full functionality of qfminim, in particular the ability to find short vectors for a non-integral quadratic form.

Currently,
short_vector_list_up_to_length
returns a listL
such thatL[i]
is a list of vectors of lengthi
. Clearly, we can no longer do this with non-integral quadratic forms. What do you propose we do in that case? Add a flag to return simply a list instead of a list of lists?
