Screamer
A platform independent LISP library that extends the language to support nondeterministic programming, but extensions include (an optional) constraint programming model, backtracking (both well known Prolog features), undoable side-effects, binding propagation, boolean constraint propagation, generalized forward checking, propagation of bounds, and unification. The system is complete enough to many users treating it as a separate variant of LISP under the name Nondeterministic Lisp.
Screamer+
Screamer+ is a small constraint solver add on to Screamer, although functional it has never really taken off as even though it is open source it has an explicit "do not redistribute without a written permission" clause alongside a non functioning e-mail address which has meant it is fast disappearing off the net.
Arno
Torsten Anders created a nondeterministic programming extension to Common Music called Arno (presumably named after Arno Babajanian) that is based on the Screamer package, since Arno does not seem to be downloadable and as Common Music no longer has a living OS/2 port this is all academic anyway. Anders later moved his attention from LISP the OZ multiparadigm programming language (now known as Mozart).
