Pretty sure
average_reward = self.value / self.visits
is redundant!

Very cool implementation! Do we also expect this implementation to be vended as another langchain_experimental agent? There are some pretty cool implementations there, for example tree of thought (which this one seems to be better than), along with reinforcement chain, plan and execute, and fallacy removal.

Totally the same code except I used a hosted ollama model to replace gpt-4o. Then the following error occurred.

   28 @as_runnable
    29 def reflection_chain(inputs) -> Reflection:
    30     tool_choices = reflection_llm_chain.invoke(inputs)
---> 31     reflection = tool_choices[0]
    32     if not isinstance(inputs["candidate"][-1], AIMessage):
    33         reflection.found_solution = False
