A non-standard finite difference scheme for Burgers-Fisher equation

چکیده مقاله

In this paper, we present a non-standard finite difference(NSFD) scheme for Burgers-Fisher equation. In continuation the main properties of NSFD scheme, i.e., positivity and bound- edness, are established for proposed NSFD scheme. Numerical experiments are presented to verify the accuracy and efficiency of NSFD scheme.
