Current research examines the economic, social, cultural, policy, educational and promotional factors in using sustainable agriculture operations. Research is an applied type and its method is correlation. The statistical population consisted of 102 members of Iran Potato Cultivars. Data were collected using a census method and a questionnaire was used. The Cronbach's alpha coefficient was obta...

Online Newton step algorithms usually achieve good performance with less training samples than first order methods, but require higher space and time complexity in each iteration. In this paper, we develop a new sketching strategy called regularized frequent direction (RFD) to improve the performance of online Newton algorithms. Unlike the standard frequent direction (FD) which only maintains a...

Developing new and efficient numerical integration techniques is of great importance in applied mathematics computer science. Among the variety available methods, multistep ODE solvers are broadly used simulation software. Recently, semi-implicit proved to be an compromise between implicit explicit solvers, multiple high-performance methods were proposed. However, computational efficiency any s...

We investigate the parallel implementation of the diagonal implicitly iterated Runge Kutta DIIRK method an iteration method based on a predictor corrector scheme This method is appropriate for the solution of sti systems of ordinary di erential equations ODEs and provides embedded formulae to control the stepsize We discuss di erent strate gies for the implementation of the DIIRK method on dist...

This report is devoted to the study and to the comparison of methods for estimation of the local error and for adaptive step-size control when solving the generalised nonlinear Schrodinger equation (GNLSE) in optics by the Interaction Picture (IP) method or by the Symmetric Split-Step (S3F) method. Namely, we propose and study the use of an embedded Runge-Kutta method to solve the nonlinear pro...

An SQP algorithm is presented for solving constrained nonlinear programming problems. The algorithm uses three stepsize strategies in order to achieve global and superlinear convergence. Switching rules are implemented that combine the merits and avoid the drawbacks of the three stepsize strategies. A penalty parameter is determined using an adaptive strategy that aims to achieve sufficient dec...

When the stepsize in Runge-Kutta codes is restricted by stability, an uneven pattern of stepsizes with many step rejections is frequently observed. A modiied strategy is proposed to smooth out this type of behaviour. Several new estimates for the dominant eigenvalue of the Jacobian are derived. It is shown that such estimates can be used, in a strictly controlled way, to improve the stepsize st...

In this paper, we extend the improved pointwise iteration-complexity result of a dynamic regularized alternating direction method of multipliers (ADMM) for a new stepsize domain. In this complexity analysis, the stepsize parameter can even be chosen in the interval (0, 2) instead of interval (0, (1 + √ 5)/2). As usual, our analysis is established by interpreting this ADMM variant as an instance...

Variational inclusion is an important general problem consisting of many useful problems like variational inequality, minimization and nonlinear monotone equations. In this article, a new scheme for solving proposed the uses inertial relaxation techniques. Moreover, self adaptive, that is, stepsize does not depend on factorial constants underlying operator, instead it can be computed using simp...
