In “Nonasymptotic Analysis of Monte Carlo Tree Search,” D. Shah, Q. Xie, and Z. Xu consider the popular tree-based search strategy, Search (MCTS), in context infinite-horizon discounted Markov decision process. They show that MCTS with an appropriate polynomial rather than logarithmic bonus term indeed leads to desired convergence property. The authors derive results by establishing a concentra...

When the researchers search for the earlier versions, only a few recent versions in the back volumes can be retrieved soon.
