Abstract
We compare the main features of the singularity-consistent (SC) method and the damped-least-squares (DLS) method. It is shown that both methods introduce a so-called algorithmic error in the vicinity of a singular point. The direction of this error is, however, different in each method. This is shown to play an important role for system stability
