The Convergence of Difference Boxes
1. INTRODUCTION. " Difference boxes, " also known as " diffy boxes, " are the basis for a simple mathematical puzzle that provides elementary-school students with subtraction practice. The idea's original author is unknown, although among many Texas teachers it is traced back to Professor Juanita Copley of the University of Houston, who introduced it as a problem-solving activity in professiona...
متن کاملGeneralized statistical convergence of difference sequences
*Correspondence: [email protected] 2Department of Mathematics, Aligarh Muslim University, Aligarh, 202002, India Full list of author information is available at the end of the article Abstract In this paper we define the λ(u)-statistical convergence that generalizes, in a certain sense, the notion of λ-statistical convergence. We find some relations with sets of sequences which are related t...
متن کاملLacunary Statistical Convergence of Difference Double Sequences
In this paper our purpose is to extend some results known in the literature for ordinary difference (single) to difference double sequences of real numbers.Quite recently, Esi [1] defined the statistical analogue for double difference sequences x = (xk,l) as follows: A real double sequence x = (xk,l) is said to be P-statistically ∆− convergent to L provided that for each ε > 0 P − lim m,n 1 mn ...
متن کاملOn Convergence of Emphatic Temporal-Difference Learning
We consider emphatic temporal-difference learning algorithms for policy evaluation in discounted Markov decision processes with finite spaces. Such algorithms were recently proposed by Sutton, Mahmood, and White (2015) as an improved solution to the problem of divergence of off-policy temporal-difference learning with linear function approximation. We present in this paper the first convergence...
متن کاملOn the Convergence of Difference Approximations
We present a unified treatment of explicit in time, two-level, second-order resolution (SOR), total-variation diminishing (TVD), approximations to scalar conservation laws. The schemes are assumed only to have conservation form and incremental form. We introduce a modified flux and a viscosity coefficient and obtain results in terms of the latter. The existence of a cell entropy inequality is d...
