Is this possible on PPL? If so, how is it done? Suppose I have 2 sets of input generators. I compute the convex hull/faces for both via double description. My question is, would this be "concatenation" operation? If so, it doesn't just concatenate the list of input generators and then performs double description does it?
Here's what I'm wondering, I often have in input that takes a long time to process. I was wondering if I could split the input into two perform double description. And then merge the convex hulls/hyperplanes together to get a final solution. Divide and conquer so to speak. Not sure if this would be faster than processing the input all at once.
Thanks,
M

Dear Monty,
can you please be more precise? I suggest to illustrate your idea with an example. Take a triangle in 2D, represented by a set of three generators: its vertices. Divide such a set into two subsets: two vertices in one subset, the remaining vertex in the other subset. Then explain what you want to do with the two subsets. Kind regards,
Roberto
