> [This is a newbie contributor issue: it's easy to solve for new contributors]
> HardAndSoftScore has a method isFeasible(), but it's currently hard to specify that a solver should terminate when a feasible score is attained, because you have to use Integer.MIN_VALUE:
> {code}
> <termination>
>   <scoreAttained>0hard/-2147483648soft</scoreAttained>
> <termination>
> {code}
> Adjust org.drools.planner.config.termination.TerminationConfig
> to support this:
> {code}
> <termination>
>   <hardAndSoftScoreFeasible>true</hardAndSoftScoreFeasible>
> <termination>
> {code}
> And copy org.drools.planner.core.termination.ScoreAttainedTermination
> to org.drools.planner.core.termination.HardAndSoftScoreFeasibleTermination
> to implement it.
> Note: the Score will need to be cast to HardAndSoftScore.
> Bonus points: write a unit test for it (for inspiration, look at PlanningEntityTabuAcceptorTest).
