Graph of Thoughts GoT
Generalises Tree of Thoughts to a DAG — thoughts can merge, aggregate, refine each other. ETH Zürich paper August 2023.
Differs from ToT: a node can have multiple parents (information aggregated from several branches). Example: in sorting tasks, GoT splits → sorts subparts → merges back. Better than ToT on some tasks (sorting, set intersection), worse on others (Game of 24). Few production uses yet — mostly research.
