RISA modified nonlinear conjugate gradient algorithm for unconstrained optimization
Conjugate gradient (CG) algorithms have played special roles in solving large scale nonlinear optimization problems
with smooth objective functions f : Rn ! R. Search directions in the CG algorithms are generated by the sequence

A Parametric Linearization Approach for Solving Zero-One Nonlinear Programming Problems
In this paper a new approach for obtaining an approximation global optimum solution of zero-one nonlinear programming (0-1 NP) problem which we call it Parametric Linearization Approach (P.L.A) is proposed. By using this approach the problem...
A meshless local Petrov–Galerkin method for nonlinear dynamic analyses of hyper-elastic FG thick hollow cylinder with Rayleigh damping
This paper is devoted to the geometrically nonlinear analysis of a functionally graded (FG) thick hollow cylinder with Rayleigh damping. The hollow cylinder is subjected to axisymmetric mechanical shock loading on its bounding surfaces. First...
An optimization method for solving the two dimensional nonlinear Fredholm integral equations of the second kind
In this paper we use measure theory to solve some nonlinear Fredholm integral equations of the second kind...
A Comparison of Neural Network and Nonlinear Regression Predictions of Sheep Growth
recorded from birth to approximately 150th days of age. About 6 nonlinear regression forms of von Bertalanffy, Gompertz, Logistic (with 3 and 4 parameters) Brody and Richards were employed as counterparts to ANN. Goodness of fit and accuracy of the models...
Head-on collision of electron-acoustic solitary waves in a plasma with superthermal hot electrons
The head-on collision between two electron-acoustic solitary waves in an unmagnetized plasma is investigated, including a cold electron fluid, hot electrons obeying a superthermal distribution and stationary ions. By using ...
On Generalized Convexity of Nonlinear Complementarity Functions
In this paper, we study some properties of quasiconvex nonlinear complementarity functions. However, we prove that a nonlinear complementarity function cannot be pseudoconvex. As a consequence of this, we show that every convex nonlinear...
Numerical solution of nonlinear optimal control problems using nonlinear programming
To solving nonlinear control problems and especially nonlinear optimal control problems (NOCP), classical methods are not usually efficient. In this paper we introduce a new approach for solving this class of problems by using Nonlinear Programming...
A Comparison between Energy Balance Method and Coupled Homotopy-Variational Approach to a Nonlinear Free Vibration of a System with Inertia and Static Type Cubic Nonlinearity
The present paper deals with two different analytical methods to a system with inertia and static
type cubic nonlinearities. The free vibration of a mass grounded by linear and nonlinear springs in series is
modeled, and a comparison...
A new method for solving a system of the nonlinear equations
In this paper we use measure theory in the discrete case to solve a wide range of the
nonlinear equations systems. First, by defining an error function, we transform the
problem to an optimal control problem in discrete case. The new...
