The closed-form wave solutions to the time-fractional Burgers’ equation have been investigated by use of two variables G ′ / , 1 -expansion, extended tanh function, and exp-function methods translating...

We describe four algorithms for neural network training, each adapted to different scalability constraints. These algorithms are mathematically principled and invariant under a number of transformations in data and network representation, from which performance is thus independent. These algorithms are obtained from the setting of differential geometry, and are based on either the natural gradi...

The nonlocal symmetry of the new (3+1)-dimensional Boussinesq equation is obtained with truncated Painlevé method. can be localized to Lie point for prolonged system by introducing auxiliary dependent variables. finite transformation related integrable studied. Meanwhile, proved consistent tanh expansion method and many interaction solutions among solitons other types nonlinear excitations such...

initiated by Dodd and Bullough [1] and Žiber and Šabat [2], plays a significant role in many scientific applications such as solid state physics, nonlinear optics, and quantum field theory. There are many research works for Dodd-Bullough equation in the last decades. It is shown thatDodd-Bulloughdetermines the intrinsic geometry of the two-dimensional affine sphere in the three-dimensional unim...

This article uses two separate approaches to find reliable and estimated solutions for the weakly nonlinear shallow-water wave model, which explains these waves are spreading in a thin dispersive medium. Exact achieved by utilizing an expanded tanh expansion Adomian decomposition (ADM.). We also evaluate demonstrate how closely they are; all convincing persuasive partial differential equations.

Genetic programming (GP) of four levels complexity, including artificial neural networks the hyper-tanh activation function (ANN-Hyper-Tanh), sigmoid (ANN-Sigmoid), evolutionary polynomial regression (optimized with genetic algorithm) (EPR), and intelligent techniques have been used to predict erodibility lateritic soil collected from an erosion site treated hybrid cement. Southeastern Nigeria ...

In this paper, we applied Exp-function method to some nonlinear evolution equations. The solution procedure of this method, by the help of symbolic computation of Matlab, Mathematica or so on, is of utter simplicity. The obtained results show that Exp-function method is very powerful and convenient mathematical tool for nonlinear evolution equations in science and engineering. Key WordsExp-func...
