In this paper, we present a primal-dual interior-point algorithm for convex quadratic programming problem based on a new parametric kernel function with an hiperbolic–logarithmic barrier term. Using the proposed kernel function we show some basic properties that are essential to study the complexity analysis of the correspondent algorithm which we find it coincides with the best know iteration bounds for large-update method, namely, O (√ n log n log n/ε) by a special choice of the parameter p > 1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
