Tree of Thoughts vs Graph of Thoughts (EXPLAINED)
Hard reasoning prompt architectures that explore, evaluate, and merge intermediate thought states beyond linear chain-of-thought.
TL;DR — Quick Answer
Tree of Thoughts expands reasoning as a branching search tree with explicit evaluation and backtracking at each node. Graph of Thoughts allows thoughts to merge, reuse, and reference each other as a DAG, reducing redundant exploration. Use ToT for puzzles with clear branching decisions; GoT when subproblems overlap or partial solutions should combine.
