Class TreeOfThoughtHandler

Namespace
LMKit.Agents.Planning
Assembly
LM-Kit.NET.dll

Planning handler that implements Tree-of-Thought (ToT) reasoning.

Explores multiple reasoning paths, evaluates intermediate states, and selects the most promising branches. Best for problems with multiple valid solution paths where exploration can find better solutions than linear reasoning.

Remarks

Tree-of-Thought Process

  1. Generate: Produce multiple candidate thoughts/approaches.
  2. Evaluate: Score each candidate for promise/correctness.
  3. Select: Choose the best candidate(s) to expand further.
  4. Repeat: Continue until a solution is found or depth limit reached.

Note: This is a simplified single-path implementation that generates and evaluates alternatives sequentially. Full tree exploration requires more complex state management.
