I've coded and tested sparse lookahead in a trading algorithm before using a comprehensive example as a guide. Do you know of any comprehensive walkthrough examples implementing a UCT scenario that I can use to implement and verify my results?
However, the tutorial doesn't work towards a working implementation. I think you can verify your results against benchmark problems. There are a number of good implementations around:
UCT implementation with many MDP benchmark problems: https://github.com/bonetblai/mdp-engine
My favorite implementation. The code is quite easy to read: http://www0.cs.ucl.ac.uk/staff/D.Silver/web/Applications_fil...
