Dr. F. Chipman of Acadia University will speak on
``GLIDE - An Implementation of a Family of General
Linear Methods.''
TIME: 3:30 PM
ROOM: MC 5097
ABSTRACT
Most algorithms currently used for the solution of
stiff initial value problems are based on either the
BDF methods of Curtis and Hirschfelder or implicit
Runge-Kutta methods. Many of the characteristics of
these two classes of methods are combined in the class
of general linear methods. GLIDE is an implementation
of a family of general linear methods introduced by
Butcher. Questions pertaining to the stability of
these methods, the practical estimation of errors, and
their implementation in a variable stepsize, variable
order algorithm will be considered. Work on this pro-
ject is being carried out jointly by Kevin Burrage,
John Butcher and Fred Chipman at the Department of Com-
puter Science, Auckland University.
