Sample Pareto multiplicative factors.

Parameters:

node_assets (str | list[str] | None) – Optional node asset key selector.
edge_assets (str | list[str] | None) – Optional edge asset key selector.
node_distribution (float) – Default Pareto alpha for selected node assets.
edge_distribution (float | None) – Default alpha for selected edge assets. When omitted, node_distribution is reused.
node_asset_distributions (dict[str, float] | None) – Optional per-node-asset alphas.
edge_asset_distributions (dict[str, float] | None) – Optional per-edge-asset alphas.
minimum (float) – Lower bound after applying the sampled multiplier.
node_ids (list[str] | None) – Optional explicit node identifiers to mutate.
node_filter (NodeFilter | None) – Optional predicate receiving (node_id, data).
edge_ids (list[tuple[str, str]] | None) – Optional explicit edge identifiers to mutate.
edge_filter (EdgeFilter | None) – Optional predicate receiving (source, target, data).

Returns:

Policy that multiplies selected numeric assets by Pareto samples.

Return type:
