Short Contributions a Note on the Normal Power Approximation
The normal power (NP) approximation essentially approximates the random variable X as the quadratic polynomial X x Y+y(Y-\)/6 where X = (X-fi)/a is the standardized variable, Y ~ N(0, 1), and /z, a y are the mean, variance skewness of X respectively. The coefficients of this polynomial are not determined by equating the lower moments. It is shown that matching these moments does not improve the...
متن کاملA note on approximation conditions, standard triangularizability and a power set topology
The main result of this article is that for collections of entry-wise non-negative matrices the property of possessing a standard triangularization is stable under approximation. The methodology introduced to prove this result allows us to offer quick proofs of the corresponding results of [B. R. Yahaghi, Near triangularizability implies triangularizability, Canad. Math. Bull. 47, (2004), no. 2...

15 صفحه اولA Note on the Power of Truthful Approximation Mechanisms
We study the power of polynomial-time truthful mechanisms comparing to polynomial time (non-truthful) algorithms. We show that there is a setting in which deterministic polynomialtime truthful mechanisms cannot guarantee a bounded approximation ratio, but a non-truthful FPTAS exists. We also show that in the same setting there is a universally truthful randomized mechanism that provides an appr...
