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.
