Two test problems having exact solutions have been considered. To demonstrate the efficiency and accuracy of the present methods, the error norms L-2 and L-infinity with the discrete mass Q and energy E conservative properties have been calculated. The results obtained by the method have been compared with the exact solution of each problem and other numerical results in the literature, and also found to be in good agreement with each other. A Fourier stability analysis of each presented method is also investigated.eninfo:eu-repo/semantics/closedAccesscollocation methodquintic B-spline functionsRosenau-KdV-RLWtime splittingArticle3551928194310.1002/num.223872-s2.0-85065819647Q1WOS:000475985300016Q1
