In general, no X solves the equality, so it's easy to minimize X. If A is a non-zero positive multiple of B, exactly one X solves the equality, so it's again easy to minimize. If A and B vanish, choose X as the smallest positive float. I suspect you intended a slightly different problem. It's hard to guess what it is. -- http://mail.python.org/mailman/listinfo/python-list
