Applying ToT to solve a multi-step problem
ToT can be particularly effective for complex reasoning tasks. Let’s implement a ToT approach for multi-step problem solving:
def multi_step_tot(model, tokenizer, problem_steps):
full_solution = ""
for step, question in enumerate(problem_steps):
prompt = f"""Step {step + 1} of the problem:
{question}
Previous steps solution:
{full_solution}
Let's use Tree-of-Thoughts to solve this step:
"""
step_solution = pruning_tot(model, tokenizer, prompt)
full_solution += (
f"\n\nStep {step + 1} Solution:\n"
f"{step_solution}"
