Tree of Thoughts - Pytorch
Project description
Paper link Author's implementation
Introduction
Tree of Thoughts (ToT) is a powerful and flexible algorithm that significantly advances model reasoning by up to 70%. This plug-and-play version allows you to connect your own models and experience superintelligence!
Install
pip install tree-of-thoughts
Usage
import os
from tree_of_thoughts import OpenAILanguageModel, MonteCarloTreeofThoughts
api_model = "gpt-3.5-turbo"
model = OpenAILanguageModel(api_key='api key', api_model=api_model)
# Initialize the MonteCarloTreeofThoughts class with the model
tree_of_thoughts = MonteCarloTreeofThoughts(model)
# To reproduce the same results from the Tree of Thoughts paper, or even better,
# craft a one-shot chain of thought prompt for your task below:
initial_prompt = """
Input: 2 8 8 14
Possible next steps:
2 + 8 = 10 (left: 8 10 14)
8 / 2 = 4 (left: 4 8 14)
14 + 2 = 16 (left: 8 8 16)
2 * 8 = 16 (left: 8 14 16)
8 - 2 = 6 (left: 6 8 14)
14 - 8 = 6 (left: 2 6 8)
14 / 2 = 7 (left: 7 8 8)
14 - 2 = 12 (left: 8 8 12)
Input: use 4 numbers and basic arithmetic operations (+-*/) to obtain 24 in 1 equation
Possible next steps:
"""
num_thoughts = 1
max_steps = 3
max_states = 4
pruning_threshold = 0.5
solution = tree_of_thoughts.solve(

# Initialize the MonteCarloTreeofThoughts class with the model

# craft an 1 shot chain of thought prompt for your task below

"Three experts with exceptional logical thinking skills are collaboratively answering a question using the tree of thoughts method. Each expert will share their thought process in detail, taking into account the previous thoughts of others and admitting any errors. They will iteratively refine and expand upon each other's ideas, giving credit where it's due. The process continues until a conclusive answer is found. Organize the entire response in a markdown table format. The task is:
