The eciency of the frontal method for the solution of ®nite-element problems depends on the order in which the elements are assembled. This paper looks at using variants of Sloan's algorithm to reorder the elements. Both direct and indirect reordering algorithms are considered and are used in combin

A new method for classifying mountain morphology, `mountain ordering,' is proposed, and quantitative expressions for various morphological parameters of two ordered mountains in northern Japan were obtained using this method. Mountain order was defined in terms of the closed contour lines on a topog
