关于交错投影有限收敛的一个注记

A Note on the Finite Convergence of Alternating Projections

Hoa T. Bui, Ryan Loxton, Asghar Moeini

摘要:

对两个互不相交的潜在非凸集,建立了交替投影法有限收敛的充分条件。我们的结果是基于一个推广的概念,内在的横截性,到目前为止,已被限制为集与非空的交集。在多面体和闭半空间的特殊情况下,我们的充分条件定义了两个集合之间的最小距离,该距离是交替投影在单次迭代中收敛所需的。

英文摘要:

We establish sufficient conditions for finite convergence of the alternating projections method for two non-intersecting and potentially nonconvex sets. Our results are based on a generalization of the concept of intrinsic transversality, which until now has been restricted to sets with nonempty intersection. In the special case of a polyhedron and closed half space, our sufficient conditions define the minimum distance between the two sets that is required for alternating projections to converge in a single iteration.
