Abstract: In this paper, we present a new lock-free tree data structure for parallelMonte Carlo tree search (MCTS) which removes synchronization overhead and guarantees the consistency of computation. It is based on the use of atomic operations and the associated memory ordering guarantees. The proposed parallel algorithm scales very well to higher numbers of cores when compared to the existing methods.
