GRPO for load balancing

Genuine doubt to network/communications/curious engineers, how do you employ (if so) reinforcement learning for the optimal control of backend routing.

I recently got really curious and used Go for the minimal implementation of GRPO for this problem

Here is the code

What do you think?, my framing is about the scalability with a minimal implementation of this algorithm so share with my your ideas or implementations!
