Quick question about action spaces about vdptag2.jl HOT 5 CLOSED

Hi @logankilpatrick, solvers sample actions with the rand function. Each time it is called, it generates an action with an angle between 0 and 2*pi. Does that make sense?

from vdptag2.jl.

Makes sense. What's the advantage to structuring it as it is now with the empty struct?

from vdptag2.jl.

That seems to me like the only way to do it. Did you have another alternative in mind?

from vdptag2.jl.

You are probably correct about that, I am just unfamiliar with the notion of defining an empty struct like is done above.

Ah, yeah, perhaps a better way to think about it is this: the lack of fields in the struct does not mean that it does not contain any information. The compiler knows the type, and hence knows that the angle should be sampled between 0 and 2*pi. There are two ways to encode information in a julia object. Fields encode information that is only known at runtime; the type can encode any information that is known at compile time. Since everything about this action space is known at compile time, there is no need for any fields.
