`PPA`

Module: opytimizer.optimizers.single_objective.population.ppa

A PPA class, inherited from Optimizer.

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

Constructor

PPA(params: Optional[Dict[str, Any]] = None) -> None

Parameter	Type	Default	Description
`params`	`Optional[Dict[str, Any]]`	`None`	—

compile(self, space: opytimizer.core.space._SingleObjectiveSpace) -> None

Compiles additional information that is used by this optimizer.

Parameter	Type	Default	Description
`space`	`opytimizer.core.space._SingleObjectiveSpace`		A Space object containing meta-information.

update(self, space: opytimizer.core.space._SingleObjectiveSpace, iteration: int, n_iterations: int) -> None

Wraps Parasitism-Predation Algorithm over all agents and variables.

Parameter	Type	Description
`space`	`opytimizer.core.space._SingleObjectiveSpace`	Space containing agents and update-related information.
`iteration`	`int`	Current iteration.
`n_iterations`	`int`	Maximum number of iterations.
