Partitions exactly meeting (if possible) user provided load balance constraints?

Hello,

I'm using METIS 4.0 for graph partitioning and heavily rely on partitions that
exactly meet (if possible) my load balance constraints. As far as I know
pmetis yields partitions with <= 1%, and kmetis with <= 3% load imbalance.

Is there any METIS version available that tries to exactly meet the user provided load balance
constraints? If not, is there a routine that can be adjusted appropriately?

Thanks,
Sebastian

This is something that will be there in the final 5.0.
