ncentive and virtual loss reduces the value incentive. SLBE-PUCT prevents full backpropagation when a move is especially suboptimal. Figure 16 illustrates multiple search paths being taken, with and without backpropagation. Even with these techniques to unlock parallelism, it is a challenge to efficiently coordinate multiple searches and batches and cleanly manage state while ferrying data and waiting on network evaluations.</p>
