Question Discrete Action Branches

When I've got 100 actions for my agent to choose from, is it better to create one discrete action branch with size 100 or to create 100 branches with size 1?
Does this make any difference?

 

A branch of size 1 will always choose the same single action every time. 100 of those is 100 identical choices.

You want a single branch of size 100.

(alternatively, you could have 2 branches of size 10, giving 10x10 total possible actions; or any combination of factors of 100 (that multiply together to give 100) (you can google "factorization" for more information on factors ) )

 

Thanks!
