Question
The "state-space tree" is a conceptual tool often
associated with backtracking. What does it represent?Solution
The state-space tree (or search tree) is a conceptual representation of all possible sequences of choices that an algorithm can make to solve a problem. Each node in the tree represents a partial solution, and the branches represent the possible choices to extend that solution. Backtracking explores this tree, pruning branches that don't lead to a valid solution.
