jaxgmg2_3phase_optim_state

32 RL agent checkpoints trained on the JaxGMG maze environment with discount_rate=0.98, with full optimizer state saved at each checkpoint. Primary runs for the 3-phase training regime analysis. Similar to jaxgmg2_3phase_unique but with optimizer state logging enabled.

• 16 runs with alpha=0.6 (run_id 15-30)
• 16 runs with alpha=1.0 (run_id 15-30)

Sweep

run_id sweep: 15-30 for each alpha value. Seed is derived from run_id via: seed = int(discount_rate*100)*10000 + int(alpha*10)*100 + run_id e.g. alpha=0.6, run_id=15 -> seed=980615; alpha=1.0, run_id=15 -> seed=981015.
