👉 Reknotting is a method used in the field of computer science and artificial intelligence to represent a tree data structure. It was developed by Richard Bellman in 1956, and it is named after the method he used for computing the shortest path between two nodes in a graph. The reknotting method involves recursively traversing the tree and constructing a list of all possible paths from a given node to any other node. Reknotting can be applied to various types of trees
