I am sure there are other more subtle ways to go about it but this seems about as fast as I can make it for a general brute-force solution (0.11s)
This one seems to work for the large test case, too, although it is not a general solution [for size(p,1)>100 it only tests corner points].
Remove the polynomials that have positive real elements of their roots.
