There is also an example there with the observer pattern.

I mean why you want to know? Or you just want to know?
In the GoF's Patterns, you'll see that Strategy and State have exactly the same class diagram.
They differ in their intent: Strategy is a "flexible alternative to subclassing". It allows you to change the behavior dynamically with composition. State is "an alternative to putting lots of conditionals in your context". It encapsulate behaviors in State objects that can be changed dynamically.
Hope it helps,
