Subject: Build up a given matrix from a set of matrices From: Matthew Date: 16 Jun, 2013 20:16:09 Message: 1 of 11 
Given an (Nx2) matrix, A, (row size is userset as N), and a separate set, U, of distinct matrices or rowvectors all having M=2 columns, but with varying rowsizes, find all possible nonintersecting constructions of the given matrix from the set of small smaller matrices/row vectors. The set of matrices/row vectors need not be exhausted, meaning that some of these matrices/row vectors may not be used in any construction of the given matrix, A.

Well, this is nothing to do with your algorithm as such. But the first thing that occurs to me is that you could easily convert each row into a single number; suppose, for instance, your integers are both int8; you could then make that a single int16, e.g.,

P.S. Could you post your algorithm that works for smaller sizes, just so I can make sure I've understood the problem correctly?

Any suggestions or ideas? Anyone?
