IDeC — Convergence independent of error asymptotics

BIT, 1987
The method of iterated defect correction [cf. \textit{R. Frank}, Numer. Math. 25, 409-419 (1976; Zbl 0346.65034) and ibid. 27, 407-420 (1977; Zbl 0366.65034)] is applied to the boundary value problem \(y''(t)=f(t,y(t))\) \(t\in (0,1)\), \(y(0)=A\), \(y(1)=B\), where \(\partial /\partial yf(t,y)\geq 0\), and analyzed for efficient and highly accurate ...

Asymptotic convergence results

1987
Essential to the convergence proof for the homogeneous algorithm is the fact that, under certain conditions, the stationary distribution of a homogeneous Markov chain exists. The stationary distribution is defined as the vector q whose i-th component is given by [FELL50] $${q_i} = \mathop {\lim }\limits_{k \to \infty } \Pr \{ X(k) = i|X(0) = j\} ,$$

Asymptotic Convergence in Quantum Scattering Theory

Journal of Computational Methods in Sciences and Engineering, 2001
The key problem in quantum scattering theory is the probability conservation, i.e., the unitarity of the S-matrix, which connects the initial with the final state of evolution of the considered physical system. This problem is not possible to solve if the scattering states neglect the so-called asymptotic convergence problem, which require that the ...

Asymptotically convergent switching differentiator

International Journal of Adaptive Control and Signal Processing, 2019
SummaryA novel switching differentiator with a considerably simplified form is proposed. Under the assumption that the time‐derivative of a time‐varying signal has a Lipschitz constant, it is shown that estimation error is asymptotically convergent to zero. The estimated derivative shows neither chattering nor peaking phenomenon.

THE CONVERGENCE RATES OF ASYMPTOTICALLY BAYES DISCRIMINATION

Acta Mathematica Scientia, 1985
Let \(P_ D(e)\) be the Bayes discrimination which minimizes the error probability, and \(P_{D_ n}(e)\) be the conditional error probability given the training samples. Here \(D=D(x)=p_ 1f_ 1(x)-p_ 0f_ 0(x)\), where \(p_ j=P(\theta =j)\), \(j=0,1\), for the population (X,\(\theta)\) in \(R^ d\), and \(f_ j(x)\) is the conditional density function of X ...

A convergence theorem for asymptotic contractions

Journal of Fixed Point Theory and Applications, 2008
We show that to each asymptotic contraction T with a bounded orbit in a complete metric space X, there corresponds a unique point x* such that all the iterates of T converge to x*, uniformly on any bounded subset of X. If, in addition, some power of T is continuous at x*, then x* is a fixed point of T.

Asymptotic convergence of transmission energy forms

2003
Summary: We consider second-order transmission problems for prefractal layers approximating the Koch curve. We prove, in a suitable function space, the convergence of the solutions to these problems to the solutions of the related transmission problems on the fractal asymptotic curve.

Asymptotic convergence of genetic algorithms

Advances in Applied Probability, 1998
We study a markovian evolutionary process which encompasses the classical simple genetic algorithm. This process is obtained by randomly perturbing a very simple selection scheme. Using the Freidlin-Wentzell theory, we carry out a precise study of the asymptotic dynamics of the process as the perturbations disappear.

Asymptotic Convergence and the Coulomb Interaction

Journal of Mathematical Physics, 1964
A definition of asymptotic convergence is given for nonrelativistic time-dependent scattering problems involving Coulomb potentials. Convergence proofs have been found both for potential and for n-body multichannel scattering. For pure Coulomb potential scattering, the Mo/ller wave matrix is computed explicitly and found to have its usual meaning.
