Release Notes
Added
- Dominated cut selection -- New
"domination" method for
training.cut_selection. Deactivates cuts that are dominated at every
visited forward-pass trial point. Most aggressive strategy; configurable
via threshold (consecutive domination checks before deactivation) and
check_frequency. Includes current-iteration protection and stage-0
exemption.
- Visited states archive -- Forward-pass trial points are now always
collected in memory during training, regardless of the cut selection
method. Useful for post-hoc analysis and required by dominated cut
selection at pruning time.
exports.states config flag -- Controls whether visited states are
persisted to the policy checkpoint (policy/states/stage_NNN.bin).
Defaults to false because the archive scales as
iterations × forward_passes × stages × state_dimension × 8 bytes.
Set to true to opt in.total_visited_states in policy metadata -- The metadata.json
checkpoint file now includes a total_visited_states field.compute_effective_eta helper -- Extracted reusable helper for
inflow noise path computation, reducing duplication across forward,
backward, and lower-bound evaluation passes.
Changed
- Policy checkpoint exports all cuts -- Both active and inactive cuts
are now serialized to the policy checkpoint. The is_active flag on
each cut record and the active_cut_indices vector preserve which cuts
are currently in the LP. Previously, only active cuts were exported.
Fixed
- Inflow truncation in lower bound evaluation -- The lower bound
evaluation pass (evaluate_lower_bound) now applies the same inflow
truncation logic as the forward and backward passes. Previously,
negative truncated inflows were not applied when evaluating stage-0
openings, producing optimistic lower bounds when
inflow_non_negativity.method was "truncation" or
"truncation_with_penalty".
