when I read adaptdl_sched source code， I meat the _get_cluster_sizes function , I guess this function help for optimize the cluster resource utilization ratio. But I can not understand how it work，can anyone explain for me.

thank you very much indeed

Thanks for the inquiry! It simply calculates the size of the cluster each individual solution in the genetic algorithm uses. If cluster auto-scaling is enabled, the policy will check for the best individual solution that's in the range of acceptable cluster sizes.
