Do you have a code implementation for INUM?

Hello, thank you for sharing the code!
INUM refers to this paper: Efficient Use of the Query Optimizer for Automated Physical Design.
CoPhy divides costs into internal sub plan costs and access costs based on INUM, and models them using integer programming. Although the cophy_input_generation.py code indicates that this approach is not necessary, I am still interested in the implementation details of INUM. If there is INUM code, I would greatly appreciate it.
