title: Monte Carlo Tree Searching UCT implementation
body: <p>Can you explain me how to build the tree?</p>
  
  <p>I quite understood how the nodes are chosen, but a nicer explanation would really help me implementing this algorithm. I already have a board representing the game state, but I don't know (understand) how to generate the tree.</p>
  
  <p>Can someone points me to a well commented implementation of the algorithm (I need to use it for AI)? Or better explanation/examples of it?</p>
  
  <p>I didn't found a lot of resources on the net, this algorithm is rather new...</p>
