Operators

Each step of an evolutionary algorithm is represented by an Operator. The @define_op macro defines new operator structs with fields specified in the operator documentation. The create_op function generates new operator objects with default values for unspecified operator fields. This section provides an overview of the operators implemented so far in Jevo.jl.

Retrievers

Retrievers are a struct or function that, retrieve data from the state.

• Jevo.PopulationCreatorRetriever, used in InitializeAllPopulations
• PopulationRetriever, used in AllVsAllMatchMaker, and many others
• get_individuals, used in ClearInteractionsAndRecords

Updaters

• Jevo.ComputeInteractions!, used in Performer
• PopulationAdder, used in InitializeAllPopulations
• PopulationUpdater, currently unused because I forgot to use it
• Jevo.add_matches!, used in AllVsAllMatchMaker and SoloMatchMaker
• Jevo.RecordAdder, used in ScalarFitnessEvaluator

Matchmaker

• AllVsAllMatchMaker
• SoloMatchMaker, individuals play a match alone, used for evolutionary computing

Evaluators

• ScalarFitnessEvaluator
• RandomEvaluator

Selectors

• TruncationSelector

Reproducers

• CloneUniformReproducer

Performer

• Performer

Mutators

• Mutator, uses Jevo.mutate as its .operator.

Assertors

Assertors are operators that you can add at any point in the pipeline to check that certain aspects of the state are as expected.

• PopSizeAssertor

Reporters

• Reporter, can log data if Jevo.measure for a specified Jevo.AbstractMetric as its .operator.

Checkpointer

• Checkpointer

Initializers

• InitializeAllPopulations, uses Jevo.create as its .operator.

Miscellaneous

• CreateMissingWorkers. SLURM compatible, but only for a single node.
