class EAHistory(fitness_calculator, log_file, progress_dump, database_dump, dump_attrs)¶

Bases: object

Deals with logging the EA’s history.

fitness_calculator¶

The FitnessCalculator used to calculate fitness values.

Type: FitnessCalculator

progress_dump¶

Toggles dumping of progress.

Type: bool

database_dump¶

Toggles dumping of dp_pop.

Type: bool

progress¶

A population where each subpopulation is a generation of the EA.

Type: EAPopulation

db_pop¶

A population which holds every molecule made by the EA.

Type: EAPopulation or NoneType

dump_attrs¶

The names of attributes of the molecule to be added to the JSON.

Type: list of str, optional

Methods

`db`(self, mols)	Adds mols to `db_pop`.
`dump`(self)	Creates output files for the EA run.
`log_pop`(self, logger, pop)	Writes pop to logger at level `INFO`.

log_file_content
pop_log_content

__init__(self, fitness_calculator, log_file, progress_dump, database_dump, dump_attrs)¶: Initialize self. See help(type(self)) for accurate signature.

db(self, mols)¶

Adds mols to db_pop.

Only molecules not already present are added.

Parameters: mols (EAPopulation) – A group of molecules made by the EA.
Returns: None
Return type: NoneType

dump(self)¶

Creates output files for the EA run.

The following files are created:

progress.log
This file holds the progress of the EA in text form. Each generation is reprented by the names of the molecules and their key.

progress.json
A population dump file holding progress. Only made if progress_dump is True.

database.json
A population dump file holding every molecule made by the EA. Only made if db_pop is not None.

static log_file_content(progress)¶

log_pop(self, logger, pop)¶

Writes pop to logger at level INFO.

Parameters

logger (Logger) – The logger object recording the EA.
pop (EAPopulation) – A population which is to be added to the log.

Returns

None

Return type

NoneType

pop_log_content(self, pop, underline, fitness_values)¶

ea_run(filename, input_file)¶: Runs the EA.
