opytimizer.optimizers.misc.doa¶

Darcy Optimization Algorithm.

class opytimizer.optimizers.misc.doa.DOA(params: Optional[Dict[str, Any]] = None)¶

A DOA class, inherited from Optimizer.

This is the designed class to define DOA-related variables and methods.

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

Initialization method.

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

r¶: Chaos multiplier.

chaotic_map¶: Array of chaotic maps.

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

Compiles additional information that is used by this optimizer.

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

_calculate_chaotic_map(lb: float, ub: float) → float¶

Calculates the chaotic map (eq. 3).

Parameters:	lb – Lower bound value. ub – Upper bound value.
Returns:	A new value for the chaotic map.
Return type:	(float)

update(space: opytimizer.core.space.Space) → None¶

Wraps Darcy Optimization Algorithm over all agents and variables.

Parameters:	space – Space containing agents and update-related information.
