No weights changed, one layer block run twice: Qwen3-1.7B climbs from 42.30% to 79.61% on GSM8K
LoOPSD builds a stronger self-teacher by repeating a searched block of a model's own layers without changing any weights, then distills that teacher's predictions into a standard-path student, lifting Qwen3-1.7B on GSM8K from 42.30% to 79.61% under a 400-token thinking budget.
