Paul Huliganga 6e9546cd22 save: all experiment scripts moved from /tmp to agent/experiments/ 
Scripts in /tmp are lost on reboot and not reproducible.
All experiment scripts now committed to git with README.

Exp5 script was already gone (lost before this fix).
All others (Exp6-Exp10, overnight, wave5, etc.) now preserved.

Rule going forward: scripts saved to agent/experiments/ and committed
BEFORE running, not after.

Experiment Scripts

These scripts were used to run individual training experiments. Each corresponds to an entry in docs/TEST_HISTORY.md.

Script Experiment Key change
mountain_v5.py Exp 5 v5 reward + throttle_min=0.5, direct model.learn()
mountain_continue.py Exp 4 Continued Exp3 training
mountain_high_throttle.py Exp 3 throttle_min=0.5, old v4 reward
exp6_mountain_v5_proper.py Exp 6 v5 + termination, wrong steps_per_switch (=total)
exp7_mountain_proper.py Exp 7 v5 + termination, correct steps_per_switch=6000, had phantom car issue
exp8_mountain_clean.py Exp 8 v5 + throttle_min=0.5, single connection, correct checkpointing
exp9_mountain_v5_throttle02.py Exp 9 v5 + throttle_min=0.2, OUR BEST MODEL
exp10_two_tracks.py Exp 10 Two tracks via custom script (abandoned — used multitrack_runner.py instead)
overnight.py Overnight runs mountain-only and Trial9-repeat experiments
wave5_train.py Wave 5 generated_track only with throttle_min=0.2

Rule going forward

ALL experiment scripts must be saved here and committed to git BEFORE running. Scripts in /tmp are lost on reboot.

Running experiments

Use multitrack_runner.py directly for two-track training: python3 multitrack_runner.py --total-timesteps 90000 --steps-per-switch 6000 ...

For single-track experiments, use the pattern from exp8/exp9:

  • VecTransposeImage(DummyVecEnv([make_env])) for env creation
  • Direct model.learn() loop with manual checkpointing
  • No close_and_switch() for single track
