Description: Automatic Continuation with Deferred Corrections
The package ACDC (which is written in FORTRAN 77) is designed to solve stiff two-point boundary value
problems for ordinary di erential equations by using continuation. We note that ACDC is a modiffcation of the package TWPBVP of Cash and M. H. Wright and that many of the original
subroutines used in TWPBVP remain unchanged in the new code. ACDC has been adapted to allow
an automatic continuation strategy to be used. Furthermore, the new code incorporates implicit
Runge-Kutta formulae, based on Lobatto points,rather than the mono-implicit formulae used in
the original code. This code is a companion to the continuation code COLMOD, which implements
our continuation strategy together with a high-order collocation method.
