> After collecting the victims, traversal starts to pick each victim and add to
> the final list until we meet the preemptable resource requirements. Sum of
> the resources used by victims collected so far might fall below or exceed
> above the preemptable required resources. It is very unlikely that both are
> same and equals. To avoid “exceed above” cases, there could be a chance that
> victims waiting next in the list might be good match when compared to the
> ones processed earlier.
> How do we pick more appropriate victims to match the expected preemptable
> resources on “best fit” (resource wise) basis precisely to avoid freeing up
> resources unnecessarily?
