Where the article explains it

This is a schematic statement of the shape these tools optimize, not a reproduction of any one paper’s exact formula, but it makes the practitioner point concrete: whichever of $\alpha$ , $\beta$ , and $\gamma$ a design team weights most heavily determines where dies actually land, and a floorplan tuned only for WL is optimizing a real but incomplete objective.

The passage around this formula
