  abstract =     "Monte-Carlo Tree Search algorithms (MCTS [4, 6]),
                 including upper confidence trees (UCT [9]), are known
                 for their impressive ability in high dimensional
                 control problems. Whilst the main test bed is the game
                 of Go, there are increasingly many applications [13,
                 12, 7]; these algorithms are now widely accepted as
                 strong candidates for high-dimensional control
                 applications. Unfortunately, it is known that for
                 optimal performance on a given problem, MCTS requires
                 some tuning; this tuning is often handcrafted or
                 automated, with in some cases a loss of consistency,
                 i.e. a bad behavior asymptotically in the computational
                 power. This highly undesirable property led to a stupid
                 behavior of our main MCTS program MoGo in a real-world
                 situation described in section 3. This is a big trouble
                 for our several works on automatic parameter tuning [3]
                 and the genetic programming of new features in MoGo. We
                 will see in this paper:

                 -- A theoretical analysis of MCTS consistency;

                 -- Detailed examples of consistent and inconsistent
                 known algorithms;

                 -- How to modify a MCTS implementation in order to
                 ensure consistency, independently of the modifications
                 to the scoring module (the module which is
                 automatically tuned and genetically programmed in
                 MoGo);

                 -- As a by product of this work, we'll see the
                 interesting property that some heavily tuned MCTS
                 implementations are better than UCT in the sense that
                 they do not visit the complete tree (whereas UCT
                 asymptotically does), whilst preserving the consistency
                 at least if consistency modifications above have been
                 made.",
