In order to complete the convergence theory of nonlinear ABS algorithm
, through a careful investigation to the algorithm structure, the auth
or converts the nonlinear ABS algorithm into an inexact Newton method.
Based on such equivalent variation, the Kantorovich type convergence
of the ABS algorithm is established and the convergence conditions of
the algorithm that only depend on the initial conditions are obtained,
which provides a useful basis for the choices of initial points of th
e ABS algorithm.
