Tree

Branching reasoning topology

Definition

Mechanism

A branching Topology where multiple lines are explored simultaneously — lines of reasoning, of search, or of provenance. Allows backtracking and pruning of unpromising branches (BFS/DFS). A Tree is the constrained form of a directed acyclic graph where each non-root node has exactly one parent.

Invariants

  1. Rootedness: All nodes descend from a single root.
  2. Acyclicity: No node is an ancestor of itself.

Risks

Failure modes

None stated.

Parameters

breadth PositiveInteger, unspecified
Maximum branches explored per node. Left open at the foundation: binary trees use 2, beam search uses 50+, decision trees can be millions. Descendants specialize.
depth Integer, [1, 20]
Maximum tree depth
