Abstract

In this article, a collocation algorithm based on quintic B-splines is proposed for the numerical solution
of the non-linear generalized regularized long wave (GRLW) equation. Also, to analyse the linear
stability of the numerical scheme, the von-Neumann technique is used. The numerical approach is
discussed on three test examples consisting of a single solitary wave, the collision of two solitary
waves and the growth of an undular bore. The accuracy of the method is demonstrated by calculating
the error in the L2 and L¥ norms and the conservative quantities I1, I2 and I3. The findings are
compared with those of previously reported in the literature. Finally, the motion of solitary waves is
graphically plotted according to different parameters.
