helper_omegas module

itrails.helper_omegas.combine_by_omega(by_omega_1, by_omega_2)[source]

Function that updates an existing subpath based on the omega values, keeps the original value if it is not -1 (already a subpath), adds the new value if it is -1 (crates a subpath).

Parameters:

  • by_omega_1 (Tuple of int64.) – Original subpath.

  • by_omega_2 (Tuple of int64.) – New subpath.

Returns:

Updated subpath.

Return type:

Tuple of int64.

itrails.helper_omegas.remove_absorbing_indices(omega_dict, absorbing_key, species, tuple_omegas=UniTuple(int64, 2))[source]

Function that removes the absorbing states from the omega dictionary.

Parameters:

  • omega_dict (Numba typed dictionary.) – Dictionary of omega indices (key) and vector of booleans where each key has the states (value).

  • absorbing_key (Tuple of int64.) – Key of the absorbing states.

  • species (int64.) – Number of species.

  • tuple_omegas (Numba type, optional.) – Type of omega, defaults to nb.types.Tuple((nb.types.int64, nb.types.int64))

Returns:

Dictionary without the absorbing states.

Return type:

Numba typed dictionary.

itrails.helper_omegas.translate_to_omega(key)[source]

Function that translates a key to its omega values.

Parameters:

key (Tuple of Tuple of int64.) – Key to translate.

Returns:

Omega values.

Return type:

Tuple of int64.
