  10 The absolute tolerance used in all "are these numbers equal" and "is
  11 this number less than (or equal to) that other number" tests. The CVXOPT
  12 default is ``1e-7``, but loosening that a little reduces the number of
  13 "unknown" solutions that we get during random testing. Whether or not it
  14 improves the solubility of real problems is a question for the
