Webcomputation time as the order of splitting increases. However, the question remains as to whether higher-order extensions of the method are worthwhile to use from a computational efﬁciency point of view. Therefore, in the present study, in addition to the ﬁrst-order splitting, we consider higher-order splittings, http://hplgit.github.io/fdm-book/doc/pub/book/sphinx/._book018.html
