Understanding “Tree of Thoughts”: A New Era in Problem Solving with Language Models

by Jon Scaccia December 11, 2023

There’s a lot floating around out there about Q*, and I decided to back to what could potentially be the source paper for some of this work Tree of Thoughts: Deliberate Problem Solving with Large Language Models

In this paper, ntroduced to an innovative framework that reshapes how we think about problem-solving in the realm of artificial intelligence. Language models like GPT and PaLM have traditionally been confined to a linear, step-by-step approach in generating text and solving problems​​. While effective for many tasks, this method has limitations, particularly when it comes to complex problems requiring strategic thinking and planning.

The “Tree of Thoughts” Approach

The “Tree of Thoughts” (ToT) framework introduces a paradigm shift, moving from a linear to a more dynamic and holistic approach. This framework is inspired by human cognitive processes, specifically the “dual process” decision-making models, involving both a fast, automatic mode and a slow, deliberate mode​​. ToT mirrors this by allowing language models to explore multiple reasoning paths and evaluate different options systematically, thus mimicking the human approach to complex problem-solving​​.

Practical Implications: Game of 24 and Creative Writing

The implications of ToT are significant, particularly in tasks that require higher-order thinking. For instance, in the mathematical “Game of 24“, where players must form an equation from four numbers to reach the number 24, ToT drastically improved their problem-solving abilities. Traditional methods like GPT-4’s chain-of-thought prompting only achieved a 4% success rate, while ToT reached 74%​​.

In creative writing tasks, ToT’s ability to generate coherent passages logically flowing from given sentences shows its potential for enhancing creativity and planning in language models. This adaptability and flexibility of ToT in handling various types of problems underscore its significance​​.

The Significance of ToT in Everyday Life

What does this mean for the average person? The ToT framework marks a significant leap in the capabilities of AI, particularly in areas requiring creative and strategic problem-solving. Imagine AI that can more effectively assist in planning, writing, or even devising strategies in games or business scenarios. The potential applications are vast, from education to entertainment and beyond.

But of course, this is where people are starting to get spooked. More on that later.
