[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   ----------------- http://www.codessentials.com - Your essential software, for free! Follow us at http://twitter.com/#!/Codessentials
