ThinkNode

ThinkNode(content: str, parent: ForwardRef('ThinkNode') | None = None)

A node in a tree structure representing a step in the reasoning process.
This class implements a tree node that stores content (text describing a reasoning step), maintains parent-child relationships, tracks node statistics, and provides utilities for traversing/visualizing the reasoning path.

Parameters:

Name	Description
content	Type: str
parent	Type: ForwardRef(‘ThinkNode’) | None Default: None

Static Methods

from_dict

from_dict(data: dict[str, Any], parent: ForwardRef('ThinkNode') | None = None) -> ThinkNode

Create ThinkNode from dictionary representation.

Parameters:

Name	Description
data	dictionary containing node data Type: dict[str, typing.Any]
parent	Parent node to attach to Type: ForwardRef(‘ThinkNode’) | None Default: None

Returns:

Type	Description
ThinkNode	ThinkNode: Reconstructed node with all children

Instance Attributes

trajectory

Get a formatted string representation of the path from root to this node.
Returns:
str: A formatted string showing the question and each step in the reasoning process

Instance Methods

backpropagate

backpropagate(self, reward: float) -> None

Update the score of this node and its parents using moving average.

Parameters:

Name	Description
reward	The reward to backpropagate up the tree. Type: float

to_dict

to_dict(self) -> dict[str, Any]

Convert ThinkNode to dictionary representation.
Returns:
dict[str, Any]: dictionary containing all node attributes and recursive children

Returns:

Type	Description
dict[str, typing.Any]	dict[str, Any]: dictionary containing all node attributes and recursive children

visualize_tree

visualize_tree(self) -> None

Visualize the tree of thoughts using graphviz.
