有效集Newton方法与部分光滑性

Active-set Newton methods and partial smoothness

Adrian S. Lewis, Calvin Wylie

摘要:

不同的优化算法正确地识别,在有限的时间内,内在的约束,必须是积极的最优。类似的行为扩展到优化系统涉及部分光滑的运营商,特别是变分不等式部分光滑集。在经典的非线性规划中,这种有效集结构是牛顿型加速局部算法设计的基础。我们正式这个想法在广泛的一般性作为一个简单的线性化计划两个相交的流形。

英文摘要:

Diverse optimization algorithms correctly identify, in finite time, intrinsic constraints that must be active at optimality. Analogous behavior extends beyond optimization to systems involving partly smooth operators, and in particular to variational inequalities over partly smooth sets. As in classical nonlinear programming, such active-set structure underlies the design of accelerated local algorithms of Newton type. We formalize this idea in broad generality as a simple linearization scheme for two intersecting manifolds.
