The generalized equal width (GEW) equation is solved numerically by a meshless method based on a global collocation with standard types of radial basis functions (RBFs). Test problems including propagation of single solitons, interaction of two and three solitons, development of the Maxwellian initial condition pulses, wave undulation and wave generation are used to indicate the efficiency and accuracy of the method. Comparisons are made between the results of the proposed method and some other published numerical methods.
