Characterizing a Configuration Where Inference-Time PRM-Pruned Fragment Grafting Is Inert: Evidence from Three Reasoning LMs

A study of PRM-Pruned Fragment Grafting (PPFG) on Qwen2.5-7B-Instruct with Math-Shepherd on full MATH500 (n=500, three seeds) found the inference-time intervention statistically indistinguishable from…
