Subject: [rules-users] Drools planner: unbreakable constraint question
 

Hi,

I have a planning project that is determined by quite some constraints.
Translated in rules this results in a number of hard constraints and a number of soft constraints.
Now I have one rule (hard constraint) that simply many not be broken, never, ever.
If a planning that fails this rule would be executed, we face a lawsuit.

Of course I can (and will) do a post-evaluation to find out if this rule is broken, 
but I want to know if there is a possibility in drools planner to forcefully reject any "solution" that breaks this one rule, 
continue searching for other solutions and guarantee that the "best solution" will not propose a combination that fails this rule?

Is this possible?


Thanks,

Michiel
