trajectory

add_entry(train_perf, incumbent_id, incumbent, budget=0)

Adds entries to trajectory files (several formats) with using the same timestamps for each entry

Parameters

• train_perf (float or np.ndarray) – estimated performance on training (sub)set

• incumbent_id (int) – id of incumbent

• incumbent (Configuration()) – current incumbent configuration

• budget (float) – budget used in intensifier to limit TA (default: 0)

Return type

None

static read_traj_aclib_format(fn, cs)

Reads trajectory from file

Parameters

• fn (str) – Filename with saved runhistory in self._add_in_aclib_format format

• cs (ConfigurationSpace) – Configuration Space to translate dict object into Confiuration object

Returns

trajectory – Each entry in the list is a dictionary of the form { “cpu_time”: float, “wallclock_time”: float, “evaluations”: int “cost”: float or list of floats, “incumbent”: Configuration }

Return type

list

static read_traj_alljson_format(fn, cs)

Reads trajectory from file

Parameters

• fn (str) – Filename with saved runhistory in self._add_in_alljson_format format

• cs (ConfigurationSpace) – Configuration Space to translate dict object into Confiuration object

Returns

trajectory – Each entry in the list is a dictionary of the form { “cpu_time”: float, “wallclock_time”: float, “evaluations”: int “cost”: float or list of floats, “budget”: budget, “incumbent”: Configuration }

Return type

list
