The complexity of Philip Wolfe's method for the minimum Euclidean-norm point problem over a convex polytope has remained unknown since he proposed the method in 1974. The method is important because it is used as a subroutine for one of the most practical algorithms for submodular function minimization. We present the first example that Wolfe's method takes exponential time. Additionally, we improve previous results to show that linear programming reduces in strongly polynomial time to the minimum norm point problem over a simplex.

凸多面体中的最小欧几里得范数点:Wolfe的组合算法是指数的

SIAM计算杂志,第49卷,第1期,第138-169页,2020年1月
。菲利普·沃尔夫关于凸多面体的最小欧几里得范数点问题的方法的复杂性自1974年提出以来一直未知。之所以重要,是因为它被用作子例程函数最小化的最实用算法之一的子例程。我们提出第一个例子,沃尔夫的方法花费指数时间。此外,我们改进了先前的结果,表明线性规划在多项式时间内将单纯形上的最小范数点问题降至最小。
