This means better performing scenarios will run for longer duration, accumulating larger return. WebJul 18, 2024 · It's reward function definition is as follows: -> A reward of +2 for every favorable action. -> A reward of 0 for every unfavorable action. So, our path through the MDP that gives us the upper bound is where we only get 2's. Let's say γ is a constant, example γ = 0.5, note that γ ϵ [ 0, 1) Now, we have a geometric series which converges: graphic images of mountains
