A self-regular Newton based algorithm for linear optimization
Keywords:linear optimization, interior point methods, self-regular functions, polynomial complexity.
AbstractIn this paper, using the framework of self-regularity, we propose a hybrid adaptive algorithm for the linear optimization problem. If the current iterate is far from central path, it employs a self-regular search direction, otherwise the classical Newton search direction is employed. This feature of the algorithm allows us to prove a worst case iteration bound. Our result matches the best iteration bound obtained by the pure self-regular approach and improves on the worst case iteration bound of the classical algorithm. doi:10.1017/S1446181109000340
