For this purpose, many different methods have been constructed and developed. In this article, a new technique which is called extended modified Exp(-Omega(xi)) function method is going to be studied for seeking new exact solutions of Burger-Fisher equation and Phi Four equation. The method is capable of deriving many number of solutions. With the aid of the method, various exact solutions including trigonometric, hyperbolic and rational solutions have been obtained and using a software the graphical representation of the solutions have been presented. In conclusion, we can say that the present method can also be used for the solutions of a wide range of problems.eninfo:eu-repo/semantics/closedAccessextended modified Exp(-Omega(xi)) function methodBurger-Fisher equationPhi-four equationexact solutionsArticle12310911910.32513/tbilisi/1569463237WOS:000488049100007N/A
