Apply multiplicative gamma noise to selected node and edge assets.
- Parameters:
node_assets (str | list[str] | None) – Node assets to perturb.
edge_assets (str | list[str] | None) – Edge assets to perturb.
node_distribution (tuple[float, float]) – Default
(shape, scale)pair used for node multipliers.edge_distribution (tuple[float, float] | None) – Default
(shape, scale)pair used for edge multipliers. Defaults tonode_distribution.node_asset_distributions (dict[str, tuple[float, float]] | None) – Optional per-node-asset overrides for
node_distribution.edge_asset_distributions (dict[str, tuple[float, float]] | None) – Optional per-edge-asset overrides for
edge_distribution.minimum (float) – Lower clamp applied after perturbation.
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 gamma multiplicative noise.
- Return type:
