 	- $\varepsilon$-greedy strategy
 		- with probability $\varepsilon$ take a random action, with probability $1-\varepsilon$ take the best known actions
 		- $\varepsilon$ often starts high and decreases over time
+	- $\rho$ (regret) can be used to find how good a strategy is
+		- this is the difference between how much reward was gotten and the maximum reward possible if distributions are known ahead of time
