Hello,<br>
<br>
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.<br>
<br>
Good luck, any way.<br>

[rules-users] Drools planner: unbreakable constraint
question<br>

<br>
I have a planning project that is determined by
quite some constraints.<br>
Translated in rules this results in a number of hard
constraints and a number of soft constraints.<br>
Now I have one rule (hard constraint) that simply
many not be broken, never, ever.<br>
If a planning that fails this rule would be
executed, we face a lawsuit.<br>
<br>
Of course I can (and will) do a post-evaluation to
find out if this rule is broken, <br>
but I want to know if there is a possibility in
drools planner to forcefully reject any "solution"
that breaks this one rule, <br>
continue searching for other solutions and guarantee
that the "best solution" will not propose a
combination that fails this rule?<br>
<br>
Is this possible?<br>
