In this paper, two new fourth-order derivative-free methods for finding multiple zeros of nonlinear equations are presented. In terms of computational cost the family requires three evaluations of functions per iteration. It is proved that the each of the methods has a convergence of order four. In this way it is demonstrated that the proposed class of methods supports the Kung-Traub hypothesis...

We have given a four-step, multipoint iterative method without memory for solving nonlinear equations. The method is constructed by using quasi-Hermite interpolation and has order of convergence sixteen. As this method requires four function evaluations and one derivative evaluation at each step, it is optimal in the sense of the Kung and Traub conjecture. The comparisons are given with some ot...

Carbon monoxide, produced in the Venus atmosphere by photolysis of C02, is removed mainly by reaction with OH. The radical OH is formed in part by photolysis of H 20., in part by reaction of 0 with H02 • Photolysis of HCl provides a major source of H radicals near the visible clouds of Venus and plays a major role in the overall photochemistry. The mixing ratio of 0 2 is estimated to be approxi...

The improved versions of the Kung–Traub family and the Zheng–Li–Huang family of n-point derivative free methods for solving nonlinear equations are proposed. The convergence speed of the modified families is considerably accelerated by employing a self-correcting parameter. This parameter is calculated in each iteration using information from the current and previous iteration so that the propo...

In this paper we have constructed an optimal eighth-order method with four function evaluations to solve the nonlinear equations. The proposed method is a three-step method in which no derivative is required. Our scheme is optimal in the sense of Kung and Traub. Moreover, some test functions have been also included to confirm the superiority of the proposed method. At the end, we have presented...

Often they are high-dimensional expected values: Example: In 1995 Traub and Paskov computed values of ‘mortgage-backed obligations’. In the USA people buying a house borrow money from a bank. In return, the bank holds a ’mortgage’. US mortgages last for 30 years, and may be repaid at the end of any month, making 30 × 12 = 360 repayment possibilities. The monthly change in the interest rate is t...

This paper deals with multipoint iterations without memory for the solution of the nonlinear scalar equation (m) f (x) = 0, m ^ 0. Let P n( ) be the maximal order of iterations which use n evaluations of the function or its derivatives per step. We prove the Kung and Traub conjecture p (0) = 2 n ^ for Hermitian information. We show p (m+l)^p (m) and conjecture P n( ) = 2 . The problem of the ma...

Recent studies (Traub, Newhall, and Fuller, 1944, 1945; Seastone, 1947; Gump, 1945) on the compound hexachlorophene (G-11) (2,2'dihydroxy 3,5,6,3',5',6'hexachloro-diphenyl-methane)I have indicated a prolonged bacteriostatic effect on human skin. In order to explain this protracted effect, studies were conducted to determine whether hexachlorophene could be recovered from skin for several days f...
