The authors study the cost of estimating the norm of an inverse matrix. They conjecture that finding even a coarse error bound is as costly as that of matrix inversion itself. Conversely, any fast condition estimate must sometimes mis-estimate by a sizable amount, specified quantitatively in the paper.
