Also, these children are named: left child or right child. A very useful specialization of binary trees is binary search tree (BST) where nodes are conventionally ordered in a certain manner. By convention, the left children < parent < right children, and this ...

In particular, decision trees (DTs) provide a global view on the learned model and clearly outlines the role of the features that are critical to classify a given data. However, interpretability is hindered if the DT is too large. To learn compact trees, a …
Web2.4Monte-Carlo Tree Search Monte-Carlo tree search [3] uses Monte-Carlo simulation to evaluate the nodes of a search tree in a sequentially best- rst order. There is one node in the tree for each state s, con-taining a value Q(s;a) and a visitation count N(s;a) for each action a, and an overall count N(s) = P a N(s;a).
