Taghizadeh University of Guilan Mohammad Mirzazadeh Department of Mathematics, Faculty of Mathematical Sciences, University of Guilan, Rasht, Iran M. Eslami University of Mazandaran M. Moradi University of Guilan Journal Article 2014 01 06 This paper reflects the implementation of a reliable technique which is called $left(frac{G'}{G}right)$-expansion  ethod for  constructing exact travelling wave solutions of nonlinear partial  differential equations. The proposed algorithm has been successfully tested on two two selected equations, the balance numbers of which are not positive integers namely Kundu-Eckhaus equation and  Derivative nonlinear Schr"{o}dinger’s equation. This method is a powerful tool for searching exact travelling solutions in closed form. https://cmde.tabrizu.ac.ir/article_1199_fb3739857771654c2517f5bfd6a6baeb.pdf
