ribs.emitters.opt¶

Various optimizers that are employed across emitters.

This subpackage contains evolution strategies that inherit from EvolutionStrategyBase and gradient-based optimizers that inherit from GradientOptBase. When specifying optimizers for an emitter, one can pass in the optimizer class itself, or the string name of the optimizer, or an abbreviated name. The abbreviations are listed below.

Evolution Strategies¶

These evolution strategies inherit from EvolutionStrategyBase:

• cma_es: CMAEvolutionStrategy

• lm_ma_es: LMMAEvolutionStrategy

• openai_es: OpenAIEvolutionStrategy

• pycma_es: PyCMAEvolutionStrategy (requires pycma to be installed)

• sep_cma_es: SeparableCMAEvolutionStrategy

Gradient-Based Optimizers¶

These gradient-based optimizers inherit from GradientOptBase:

• adam: AdamOpt

• gradient_ascent: GradientAscentOpt
