In reinforcement learning, when we talk about the principle of optimality, do we assume the policy to be deterministic?

  • $\begingroup$ Hi. Can you clarify what your question is? Is it "when we talk about the principle of optimality, do we assume policy to be deterministic?" $\endgroup$

  • $\begingroup$ Yes, that's what I meant $\endgroup$ Aug 18 '20 at 10:17
  • $\begingroup$ Which "principle of optimality" are you talking about exactly? Where did you read this term? Maybe provide a reference to the book? Are you talking about the optimality of the value iteration and/or policy iteration? I heard the term "principle of optimality" only in the context of dynamic programming algorithms. $\endgroup$

  • $\begingroup$ Yes, I'm reading Sutton-Barto, Introduction to Reinforcement learning. I'm asking in the context of DP only. $\endgroup$ Aug 18 '20 at 10:22
