An Exploration takes model outputs, a distribution, and a timestep from the agent and computes an action to apply to the environment using an implemented exploration schema. action_space framework policy_configmodel num_workers worker_indexc"||_||_||_||_||_||_d|_t|jtj rs r%get_exploration_optimizerz%Exploration.get_exploration_optimizers r'sessciS)zReturns the current exploration state.

Note that some exploration components are stateless, even though they decay some values over time (e.g. EpsilonGreedy). However the decay is only dependent on the current global timestep of the policy and we therefore don't need to keep track of it.
