NUMERICAL SOLUTION VIA HAAR WAVELET APPROACH FOR BURGER'S FISHER EQUATION

        In this thesis, Haar wavelet method is implemented efficiently in finding the numerical solution of Burger's Fisher equation. This method shows rather rapid convergence than other existing methods. Illustrative examples are implemented to show the efficiency and the powerful of Haar wavelet approach. The comparison among the numerical results and the exact solution, and the solutions obtained by using some traditional methods such as variational iteration method (VIM) shows that the suggested scheme is fairly accurate and viable for solving Burger's Fisher problem.
