Webb19 apr. 2024 · In short, we can drill down backtracking to the below steps: Start from a state. If the current state is a solution, add the current state to the result. If not, try each of the possible moves from the current state. Once we have tried all the possible moves, backtrack to the previous state. WebbExample 1: The Structure of Decision Tree. Let’s explain the decision tree structure with a simple example. Each decision tree has 3 key parts: a root node. leaf nodes, and. branches.
