Hello,
I'm not a good Drools user. But i think what you can do, is to use a
high value(a value that is greater than the sum of all other possible
values associated with the soft constraints). By this way you will be
sure that a solution with this constraint violated will not be accepted
if there is another one in which the constraint is not violated. In
opposite if all your solutions violate this constraint, you will have
one with the less number of violation and that can be enhanced through
the steps of research, which can lead finally to a feasible solution.
Good luck, any way.

*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
