class
opytimizer.functions.constrained.ConstrainedFunction(pointer: List[callable], constraints: List[callable], penalty: Optional[float] = 0.0)¶ A ConstrainedFunction class used to hold constrained single-objective functions.
-
__init__(pointer: List[callable], constraints: List[callable], penalty: Optional[float] = 0.0) → None¶ Initialization method.
Parameters: - pointer – Pointer to a function that will return the fitness value.
- constraints – Constraints to be applied to the fitness function.
- penalty – Penalization factor when a constraint is not valid.
-
constraints¶ Constraints to be applied to the fitness function.
-
penalty¶ Penalization factor.
-
__call__(x: numpy.ndarray) → float¶ Callable to avoid using the pointer property.
Parameters: x – Array of positions. Returns: Constrained single-objective function fitness. Return type: (float)
