Apply additive random walks with directional persistence.
- Parameters:
node_steps (dict[str, float] | None) – Maximum additive step per node asset.
edge_steps (dict[str, float] | None) – Maximum additive step per edge asset.
node_bounds (dict[str, tuple[float | None, float | None]] | None) – Optional lower/upper bounds for node assets.
edge_bounds (dict[str, tuple[float | None, float | None]] | None) – Optional lower/upper bounds for edge assets.
momentum (float) – Fraction of the previous additive step reused at the next epoch. Must be between 0 and 1.
node_ids (list[str] | None) – Optional explicit list of node ids to target.
node_filter (NodeFilter | None) – Optional predicate to filter target nodes.
edge_ids (list[tuple[str, str]] | None) – Optional explicit list of target edges.
edge_filter (EdgeFilter | None) – Optional predicate to filter target edges.
- Returns:
A graph update policy applying momentum random walks.
- Return type:
