Re: OOPS Expert System Shell with LEX conflict resolution

Hy everybody,
I'm a newbie student of prolog. I have to develope an expert system.
For do this i want to use a forward chaining shell like OOPS described
in Amzi! Building Expert System in Prolog. I've problem trying to use
the LEX conflict resolution specifically when program call findall
the system shows this message
"ERROR: source_sink `rule _G530:_G531==>_G532' does not exist".
I can't find the bug.
Someone has a working version of Oops or other expert system shell
with conflict resolution ?
Thanks for your help.


Most Prolog systems include an implementation of Constraint Handling Rules (CHR). CHRs are forward chaining rules very similar to production rules. They do not offer all features of a full production rule system, but certainly those of OOPS. They should be far more efficient than OOPS as well. The conflict resolution is fixed and different from LEX, but in practice there should be noticeable difference.

CHeeRs,
Peter
