q2 i? Although the deterministic cycle-removal procedure runs for every topic, none of the five evaluation topics required edge removal; cycles appeared only in pilot runs on out-of-corpus topics. → Md Zabirul Islam 2026

q2 · i? · design · r2

Inspection of scaffolding-module concept graphs across the five evaluation topics, illustrated for filtered back projection with stage-labeled nodes. The article reports zero edge removals on evaluation topics and characterizes the algorithm as a safety mechanism.

"Although the cycle-break procedure runs for every topic, none of the five evaluation topics required edge removal. Cycles appeared only in pilot runs on out-of-corpus topics, suggesting that the algorithm is primarily a safety mechanism rather than a routine repair step."
