This paper addresses the local convergence properties of the affine-scaling
interior-point algorithm for nonlinear programming. The analysis of local
convergence is developed in terms of parameters that control the interior-p
oint scheme and the size of the residual of the linear system that provides
the step direction. The analysis follows the classical theory for quasi-Ne
wton methods and addresses q-linear, q-superlinear, and q-quadratic rates o
f convergence.
