I think this is right. Allocating & copying such a huge matrix repeatedly would be terrible. Perhaps we should introduce an API function to "add_constraints", which takes a list of lists, or a matrix? If a solver doesn't support such a thing, we could fall back on the brute force method. john perry > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
