alifestd_unfurl_traversal_topological_polars

alifestd_unfurl_traversal_topological_polars(phylogeny_df: DataFrame) → ndarray

List node indices in topological traversal order.

Parents are visited before children. If the dataframe is already topologically sorted, the existing row indices are returned directly. Otherwise, a topological ordering is computed.

Parameters

phylogeny_dfpolars.DataFrame or polars.LazyFrame

The phylogeny as a dataframe in alife standard format.

Must represent an asexual phylogeny with contiguous ids.

Returns

np.ndarray

Index array giving topological traversal order.
