Estimating average convergence velocity of genetic algorithms;

The estimators of parameters in distribution and overall sample number were given, and the strong convergence rate and mean square convergence rate of estimators were obtained.

L pmean convergence of Hermite-Fejér operators is investigated.

Weighted Lp mean convergence of Extended Hermite-Fejer operators based on the zeros of orthogonal polynomials with respct to the general weight and Jacobi weight is investigated.

In this paper, the mean convergence of the derivatives of Hermite - Fejer interpolation operator Q2n+1 (f, x ) based on the zeros of Chebyshev polynomial of the second kind is considered.

Effect of calculation parameters on convergence speed of one-dimensional transient heat transfer series solution;

Study on convergence speed of high order P type iterative learning control algorithm;

Analysis of convergence speed of repetitive control system;

Improvement of convergence rates for the empirical Bayes test problem in scale exponential family;

Mean convergence rate of derivatives approximation by Lagrange interpolation operators;

Making use of the formula of and the inequality of,this paper has deduced two types of probabilistic approximation of C-semigroups and the estimating of convergent rate.

It has been shown that the convergent rate .

Then,using Taylor expansion of the semigroup,Holder s inequality and estimations of moment-generating functions of some suitable random variables,some briefly probabilistic approximations and estimations of convergent rates are obtained for C-semigroups.
