基于半无限表示的LP-Newton方法在SOCP中的推广

Extension of the LP-Newton method to SOCPs via semi-infinite representation

Takayuki Okuno, Mirai Tanaka

摘要:

LP-Newton方法通过将当前点重复投影到某个相关多面体上来解决线性规划问题(LP)。在本文中,我们扩展的LP-牛顿方法的算法框架,二阶锥规划问题(SOCP)通过一个线性半无限规划(LSIP)的重新制定给定的SOCP。在扩展中,我们产生一个序列的投影到多面体锥构造的LP通过松弛LSIP获得。在较温和的假设下,证明了该算法的整体收敛性,并通过数值实验将该算法与SOCP的原对偶内点方法进行比较,考察了其效率。

英文摘要:

The LP-Newton method solves the linear programming problem (LP) by repeatedly projecting a current point onto a certain relevant polytope. In this paper, we extend the algorithmic framework of the LP-Newton method to the second-order cone programming problem (SOCP) via a linear semi-infinite programming (LSIP) reformulation of the given SOCP. In the extension, we produce a sequence by projection onto polyhedral cones constructed from LPs obtained by finitely relaxing the LSIP. We show the global convergence property of the proposed algorithm under mild assumptions, and investigate its efficiency through numerical experiments comparing the proposed approach with the primal-dual interior-point method for the SOCP.
