culebra.trainer.abc module

Abstract base classes for different trainers.

This module provides several abstract classes for different kind of trainers.

The CentralizedTrainer class supports the development of a trainer to solve a problem related to a single species. On the other hand, the DistributedTrainer class provides a base support to distribute a trainer making use a several centralized subtrainers. Two implementations of this class are also provided:

• CommonFitnessFunctionDistributedTrainer: Abstract base class for distributed trainers whose subtrainers share the same fitness function

• ParallelDistributedTrainer: Abstract base class for parallel distributed trainers

• SequentialDistributedTrainer: Abstract base class for sequential distributed trainers

Finally, some usual distributed approaches are also provided:

• CooperativeTrainer: Abstract base class for cooperative trainers

• IslandsTrainer: Abstract base class for island-based approaches
