强凸区域上有界Hessian函数的全局最大化

On Global Maximization of Bounded Hessian Functions over Strongly Convex Domains

Marius Costandin

摘要:

在本文中,我们提出了两个框架,其中一个强凸集上的有界海森函数的全局最大化可以减少到凸优化。第一个提出的框架是我们以前的论文之一的延续[11]。在$C$不属于n个圆盘中心的凸包的条件下,改进了已有的结果,给出了n个圆盘的有限交中最远点到$C \in \mathbb{R}^{n \times 1}$的多项式时间显式算法.最后,为了克服这一限制,我们提出了第二个框架,其特征在于最远的n-磁盘与$C$在凸包的有限交叉。不幸的是,第二个框架需要能够决定我们定义的多面体是否包含在交集中,这通常很难。然而,作为我们的第二个框架的一个特殊应用,我们能够在P时间解决一些实例的子集和问题的实际项目:给定一组实数决定是否有一个子集,加起来为零。

英文摘要:

In this paper we present two frameworks in which global maximization of a bounded hessian function over a strongly convex set can be reduced to convex optimization. The first presented framework is a continuation of one of our previous papers [11]. We improve the results and give an explicit algorithm for the computation in polynomial time of the farthest point in a finite intersection of n-disks to $C \in \mathbb{R}^{n \times 1}$ under the requirement that $C$ does not belong to the convex hull of the centers of the n-disks. Finally, in order to overcome this limitation we present a second framework which characterizes the furthest in the finite intersection of n-disks with $C$ in the convex hull. Unfortunately this second framework requires the ability to decide if a polytope that we define is included in the intersection, which is hard in general. However, as a particular application of our second framework we are able solve in P time some instances of the subset sum problem with real entries: given a set of real numbers decide if there is a subset which adds up to zero.
