WebSep 26, 2016 · I'm trying to solve the Mountain Car task on OpenAI Gym (reach the top in 110 steps or less, having a maximum of 200 steps per episode) using linear Q-learning (the algorithm in figure 11.16, except using maxQ at s' instead of the actual a', as required by Q-learning; I've solved it with other methods easily, the question is about linear Q-learning). WebThe implementation for the Mountain Car environment was imported from the OpenAI Gym, and the tile coding software used for state featurization was also from Sutton and Barto, installed from here. If you are reading this on my blog, you can access the raw notebook to play around with here on github. If you are on github already, here is my blog!

WebI was able to solve MountainCar-v0 using tile-coding (linear function approximation), and I was also able to solve it using a neural network with 2 hidden layers (32 nodes for each layer, so (input, hidden), (hidden, hidden), (hidden, hidden), (hidden, out) ). WebIn a one-dimensional track, the car is positioned between -1.2 (leftmost) and 0.6 (rightmost), and the goal (yellow flag) is located at 0.5. The engine of the car is not strong enough to drive it to the top in a single pass, so it has to drive back and forth to build up momentum.
