This old page [1995] gives an overview over programs to be used in connection with E.S. Andersen, Evolutionary Economics: Post-Schumpeterian Contributions, Pinter, London, 1994/1996 - especially chapter 4 and the appendix. The information is now partly outdated - try also Nelson and Winter Models Revisited [1996]

The EE book includes some information on the Maple programming language (for further information see Maple tutor, Maple books, and Maple sites). The programs cannot be run without using the Maple procedures for the generation of random numbers.
