Hi

Screamer (https://nikodemus.github.io/screamer/) is a Lisp library that:

"Screamer provides a nondeterministic choice-point operator, a backtracking mechanism, and a forward propagation facility."

Is there an equivalent library available in Smalltalk?

Thanks

Paul

Check the following: http://ss3.gemstone.com/ss/Control.html

Besides that it is very easy to implement it yourself. Check the following paper with the example source code: http://dl.acm.org/citation.cfm?id=62094&dl=ACM&coll=DL&CFID=6958...
