[PPL-devel] merging hulls

Not sure if the mailing list got my first message, but here goes...

I have an input that's a set of generators/vertices. I'd like to split the input in two and compute hyper planes for each half. How can I merge the two constraint systems to get a final set of minimized constraints?

Do I have to basically processes the whole input at once? Or point me to some literature that may address this (if it's actually possible)? I was hoping for a divide and conquer type approach to computing constraints.

Thanks,

M
