![]() ![]() In practice about 10% to 15% of visited nodes will be found eligible for this blending. tablebase hit is definive and a transposition subtree with large N is highly reliable). better than expected), and also the reliability of the sibling evaluation (e.g. The weight used in the blending depends on the mimimax consideration of giving more weight if the node was better than the node actually being visited (i.e. If so, this value (taken from the Q subtree evaluation in the case of transpositions) is blended into the value backed up higher in the tree. ![]() Specifically, when a child of a node is first visited as a leaf node, the adjacent siblings (within 3 slots and 10% prior probability distance) are also scanned to see if an evaluation is already available (via transpositions or tablebase hits). having lower policy prior probabilities). This feature can optionally be turned off via the ReducedMemoryMode option in Ceres.json or UCI, or the MaxTreeNodes setting can be used to place a hard limit on the number of nodes that are allowed to be used by any search.Ī "sibling blending" technique sometimes averages in information to newly visited nodes from their siblings not yet evaluated (i.e. This technique does increase the memory usage, but the aggressiveness is automatically tuned based on the physical RAM available in the computer. In addition, the nodes which fall out of the actual search still tree sometimes remain memory resident and available as an addition cache (reducing the number of positions actually being sent to the neural network by approximately 3%). Ceres can now avoid rebuilding the tree in a most cases (by swapping the new root position and performing some associated data structure update). Previously this overhead decreased effective search speed by approximately 11% at long time controls, now reduced to about 3%. It has features comparable to popular commercial chess software.A "root swapping" technique greatly reduces the time spent at the beginning of search of moves within a game to reorganize the search tree.
