Inquiry about the IoU Reward implementation

[RayneYael]

Hello,

Thank you for the great paper and for sharing the code.

I've been reviewing your paper on GUI Grounding and the corresponding repository. The paper mentions three reward functions: Click, IoU, and Format. The implementations for the Click and Format rewards are clear in src/grpo_grounding.py.

However, I couldn't locate the implementation for the IoU Reward within the training loop. I was wondering if this part of the code has not yet been committed, or if I may have overlooked it.

Could you please clarify?

Thanks again for your work.
