__init__(params: Optional[Dict[str, Any]] = None) → None

Initialization method.

Parameters:params – Contains key-value parameters to the mp_mutation-heuristics.

alpha

Step size.

p_mutation

Probability of mutation.

z

Percentage of width between lower and upper bounds.

sigma

List of widths.

compile(space: opytimizer.core.space.Space) → None

Compiles additional information that is used by this optimizer.

Parameters:space – A Space object containing meta-information.

update(space: opytimizer.core.space.Space, function: opytimizer.core.function.Function) → None

Wraps Satin Bowerbird Optimizer over all agents and variables (eq. 1-7).

Parameters:

• space – Space containing agents and update-related information.
• function – A Function object that will be used as the objective function.
