Notification Channel Optimizer 2D — Multi-Armed Bandit Bar Race

A government agency needs to send a citizen alert, but which channel — SMS, email, app push, or mail — will actually get read? This 2D dashboard runs a real multi-armed bandit AI that sends one synthetic message at a time, observes whether it was "opened" against a hidden per-channel true rate, and updates its running belief. Switch between epsilon-greedy and UCB1 selection strategies and watch the four channel bars race and settle, a translucent confidence-bound cap track each estimate under UCB1, and a live cumulative-regret chart trace how efficiently the AI is converging on the best-performing channel.
