Abstract : The problem of numerical reproducibility is the problem of getting the same result when a numerical computation is run several times, whether on the same machine or on different machines. The accuracy of the result is a different issue. As far as interval arithmetic is concerned, the relevant issue is the inclusion property, that is, the guarantee that the exact result belongs to the computed resulting interval.
