+## 2026-03-14 - [O(N^2) Array Operations in Loops Bottlenecking Network Generation]
+**Learning:** In Preferential Attachment graph generation (`build_graph` for `SCALE_FREE` networks), repeatedly slicing, sampling, and sorting the full array of existing nodes (`node_ids[:i]`) within an outer loop scales terribly, causing a massive O(N^2) bottleneck. Generating even modest graphs (50k-100k nodes) took an unacceptably long time (~11-40s).
+**Action:** When implementing probabilistic selection where weight is proportional to item count (like node degree), use a flat "roulette wheel" array where each item appears once per point of weight. Randomly choosing from this list with `random.choice` is exact, avoids expensive mapping/sorting, and reduces the selection step to O(1) time complexity.
