The Multi-armed Bandit

The Multi-Armed Bandit

Now… what if you need to test MORE than just A and B? What if you’ve got, say… FOUR options? That’s when the Multi-Armed Bandit takes the stage.

Here’s how it plays out:

• It tests all the four contenders on JUST 20% of your audience.
• Once it finds the TOP contender, that winner gets served to the remaining 80% of your audience.

The result? Maximum gains. Minimal waste. And the testing? It never stops. The Bandit just keeps searching for… something even better.
