Approximation hardness of dominating set problems in bounded degree graphs [PDF]

open access: yes, 2008
We study approximation hardness of the Minimum Dominating Set problem and its variants in undirected and directed graphs. Using a similar result obtained by Trevisan for Minimum Set Cover we prove the first explicit approximation lower bounds for various

Local RBF approximation for scattered data fitting with bivariate splines [PDF]

open access: yes, 2005
In this paper we continue our earlier research [4] aimed at developing effcient methods of local approximation suitable for the first stage of a spline based two-stage scattered data fitting algorithm.

SDE WEAK APPROXIMATION LIBRARY (SDE WA) (VERSION 1.0) [PDF]

open access: yes
In application of mathematical finance to practical problems, weak approximation of stochastic differential equations (SDEs) is one of the most important themes.In probabilistic approach to this problem, the Euler-Maruyama scheme which is a first-order ...

Odd Log-Logistic XGamma Model: Bayesian and Classical Estimation with Risk Analysis Utilizing Reinsurance Revenues Data

open access: yesJournal of Statistical Theory and Applications (JSTA)
Effective risk exposure descriptions can be made using continuous distributions. To illustrate the level of exposure to a certain danger, it is better to use a single number, or at the very least, a small set of numbers.
