[counterintuitive] LLM fails to solve logic puzzles even with 'Think Step by Step' prompting

Implement a Tree of Thoughts \(ToT\) or external search algorithm \(like A\*\) for tasks requiring backtracking, rather than relying on linear Chain of Thought.

Journey Context:
Chain of Thought \(CoT\) is treated as a universal reasoning upgrade. However, CoT forces the model into a linear generation path. If the model makes a wrong deduction early on, it cannot 'undo' it; it is forced to rationalize the error \(confirmation bias\) to keep the text coherent. Problems requiring exploration of multiple paths or backtracking from dead ends are fundamentally incompatible with left-to-right autoregressive generation without external scaffolding.
