Tree of Thoughts (ToT) 2026: Deep Turkish Technical Guide — New Paradigm for Complex Problem Solving

## 1. Introduction Tree of Thoughts - LLMs generate parallel thought branches in tree structure, search via BFS/DFS/Beam Search. Yao et al. 2023. ## 2. Benchmark Results Game of 24: GPT-4 CoT 4%, ToT 74%. Creative Writing: 6.93 to 7.56 coherence. 5x5 Crosswords: 16% to 60%. ## 3. 4 Components Thought Decomposition, Thought Generation, State Evaluation, Search Algorithm. ## 4. CoT vs ToT vs GoT CoT linear, ToT tree, GoT graph with aggregation. ## 5. Implementation LangGraph state machine, BFS recommended, max_depth 3-7, beam_width 3-5. ## 6. Cost 10-50x CoT. Worth it for critical complex problems. ## 7. Conclusion ToT essential for complex problem solving. Production via LangGraph.
