A class of RK methods consistent of order at least 2 is offered so that the unity of thetwo-stage Gauss, Radau and Lobatte formulae is achieved. Based on the class of axmethods exponentially fitted ax
In this paper, we combine implicit RK method with implicit linear multistep methodto propose a class of multistep interpolation methods which make use of the derivativesat the point of t.--k+j (j ~ 1,
The algorithm is introduced in this paper, it not only applies simplex method butalso remains the original form of the constraint matrix of the problem in the processof solving the block-angular struc
In this paper we present a simple and practical direct method solving a class ofaffine variational inequalities on rectangle domain. The algorithm is of polynomialtime. And its multiplication work is
This paper presents a new CG-type algorithm for solving large linear systems. It isobtained from a subclass of the ABS algorithm-Voyevodins CG method by choosingthe parameter matrix B in some special
The algebraic expressions describing the geometric properties of mesh curves aregiven. The control functions concering above properties are introduced and functionalsshowing those properties are const
In this paper, we present a barrier function algorithm for bound constrainted minimization. Under milder conditions, we prove the convergence of the algorithm. Inaddition, we also carry out some numer
Parallel computation for generalized eigenvalue problem is one of the fundalmentalproblems in large-scale engineering computation. Zhou Shuquan, Deng Shaozhong andZeng Lan have made a systematic and d
In this paper, the method with high-order accuracy was presented for a kind ofnonlinear sigular perturbation problems. The numerical tests demonstrate that only afew grid points are enough for the num
The fuzzy estimation method is developed based on theory of probability and statistics and the results are utilizied in state estimation of stochastic system. By means ofthe approach, a fuzzy filterin
