Judge verdict

Evidence use

3 / 4

Selection cites both observed development losses and compares them correctly; evidence is limited to two runs.

e00005 ↓e00010 ↓e00011 ↓

Experiment choice

3 / 4

A baseline and a controlled alpha change with seed fixed provide a clear, relevant comparison, but exploration is narrow.

e00001 ↓e00006 ↓

Feedback integration

2 / 4

Final choice incorporates the measured losses correctly; no explicit result-driven rationale for the second experiment is supplied.

e00005 ↓e00006 ↓e00010 ↓e00011 ↓

Reproducibility

2 / 4

Script filenames, alpha values, seed, and valid executions are recorded, but code contents, data split, and environment are not supplied.

e00001 ↓e00006 ↓e00005 ↓e00010 ↓

Final selection

4 / 4

Chooses alpha=10 using its lower observed development loss and explicitly cites both results; no unsupported performance claim is visible.

e00005 ↓e00010 ↓e00011 ↓
