Approximate BDD Minimization by Weighted A. [PDF]

open access: yes2009 IEEE International Symposium on Circuits and Systems, 2009
Reduced ordered Binary Decision Diagrams (BDDs) are a data structure for efficient representation and manipulation of Boolean functions. They are frequently used in logic synthesis. The size of BDDs depends on a chosen variable ordering, i.e. the size may vary from linear to exponential, and the existence of a polynomial algorithm to approximate the ...

On Weighted Polynomial Approximation With Gaps [PDF]

open access: yesNagoya Mathematical Journal, 2005
Let α be a nonnegative continuous function on ℝ. In this paper, the author obtains a necessary and sufficient condition for polynomials with gaps to be dense in Cα, where Cα is the weighted Banach space of complex continuous functions ƒ on ℝ with ƒ(t) exp(−α(t)) vanishing at infinity.

Construction of a New Family of Baskakov Operators Based on Negative λ-Binomial Distribution

open access: yesMathematics
We propose the λ-Baskakov operator based on λ-binomial distribution, which is a new Baskakov-type operator. First, the moments and the central moments for them and their quantitative properties are computed.

Approximate Weights

open access: yesThe Annals of Mathematical Statistics, 1948
The greatest fractional increase in variance when a weighted mean is calculated with approximate weights is, quite closely, the square of the largest fractional error in an individual weight. The average increase will be about one-half this amount. The use of weights accurate to two significant figures, or even to the nearest number of the form: 10, 11,

Riemann–Liouville Fractional Integral Form of Modified Baskakov-Type Operators: Approximation Properties and Statistical Convergence

open access: yesMathematics
In this paper, a generalized sequence of Baskakov operators connected to the Riemann–Liouville fractional integral is introduced. These sequences of operators deal with smooth approximation behavior in a wider class, i.e., a class of measurable functions

A new approach to nonlinear singular integral operators depending on three parameters

open access: yesOpen Mathematics, 2016
In this paper, we present some theorems on weighted approximation by two dimensional nonlinear singular integral operators in the following form: Tλ(f;x,y)=∬R2Kλ(t−x,s−y,f(t,s))dsdt,(x,y)∈R2,λ∈Λ,$${T_\lambda }(f;x,y) = \iint\limits_{{\mathbb{R}^2}}K_ ...

Chebyshev Approximations by Least Squares Method

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
We consider the problem of linear approximation in the form of the minimization problem of the weighted Chebyshev norm, and that in the form of the minimization problem of the weighted Euclidean norm of the residual vector.

Approximation by weighted polynomials

open access: yesJournal of Approximation Theory, 2003
The paper is devoted to the study of approximation by weighted polynomials. The author proves that if \(xQ'(x)\) is increasing on \((0,\infty)\) and \(w(x)= \exp(-Q(x))\) is the corresponding weight on \([0,\infty)\), then every continuous function that vanishes outside.
