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. February 21, 1984
