Dear All Thanks for the kind replies What I am concerned is, my rules is always dynamically changes over time(e.g. CPU availability/utilisation) -with that, I cannot hard coded on the programming coding. Even their template/"deftemplate" might be changes(e.g. new software properties/a totally new hardware-such as any new instrument attached to the computer system)
Is that possible with JCHR? Any suggestions are welcome Cheers mnoor On Nov 15, 2007 5:09 PM, Hal Hildebrand <[EMAIL PROTECTED]> wrote: > What you are describing is constraint programming.
