Each arm has a hidden true conversion rate the algorithm never sees. UCB1 tracks per-arm pulls and average reward, then each round picks the arm with the highest score avg_reward + √(2·ln(N)/n_i) — balancing trying the best-so-far arm (exploitation) against under-sampled arms whose confidence bound is still wide (exploration). The grey towers show a naive uniform 50/50-style baseline run on the identical simulated conversion draws for a fair comparison.
