Flow is created by and actively developed by members of the Mobile Sensing Lab at UC Berkeley (PI, Professor Bayen). As a TA of “Introduction to Artificial Intelligence” in spring 2015 and 2016, I googled these materials and found it interesting for teaching, so I suggested applying these to our course. Should return 0.0 if we have never seen a state, where the max is over legal actions. Compute the best action to take in a state. and then act according to the resulting policy. io/large-scale-curiosity/.
