研究两类广义控制问题的复杂性: k-步长控制问题和k-距离控制问题, 证明了k-步长控制问题在弦图和平面二部图上都是NP-完全的. 作为上述结果的推论, 给出了k-距离控制问题在弦图和二部图上NP-完全性的新的证明, 并进一步证明了k-距离控制问题在平面二部图上也是NP-完全的.

We show that unless P=NP, there exists no polynomial time (or even pseudo-polynomial time)
algorithm that can decide whether a multivariate polynomial of degree four (or higher even
degree) is globa...

Weighted low-rank approximation (WLRA), a dimensionality reduction technique for data anal-
ysis, has been successfully used in several applications, such as in collaborative filtering to design reco...

Duality Gap Computational Complexity NP Completeness

In this paper, we survey research that studies the connection between the computational complexity of optimization problems on the one hand, and the duality gap between the primal and dual optimizatio...
I prove that if markets are weak-form efficient, meaning current prices fully reflect all information available in past prices, then P = NP, meaning every computational problem whose solution can be v...

NP图灵完全集的一些性质
2007/12/10
本文主要结果是:(1)P=NP 当且仅当一切 NP 图灵完全的无穷集组成一个非递归可表现的类;(2)NP=co-NP 当且仅当一切 NP 图灵完全集恰好组成一个多项式时间图灵等价类;(3)NP=co-NP 当且仅当$NP=P^{SAT}$.
