Adapts Hamiltonian trajectory lengths using a recursively doubled candidate tree and no-U-turn stopping construction, with dual-averaging step-size adaptation.
Scientific scope
Adapts Hamiltonian trajectory lengths using a recursively doubled candidate tree and no-U-turn stopping construction, with dual-averaging step-size adaptation. The reversible candidate-selection construction matters: merely stopping a trajectory at its first U-turn is explicitly not justified. HMC, slice sampling and dual averaging are inherited. Removes selected hand-tuned parameters, not all choices, diagnostics or finite-chain convergence risk;2011preprint not2014journal body.

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
