DynamicProbabilityRandomDesign #

DynamicProbabilityRandomDesign(
    probability: float, factor: float, seed: int = 0
)

Bases: AbstractRandomDesign

Interleave a random configuration according to a given probability which is decreased over time.

PARAMETER	DESCRIPTION
`probability`	Probability that a configuration will be drawn at random. TYPE: `float`
`factor`	Multiply the `probability` by `factor` in each iteration. TYPE: `float`
`seed`	Integer used to initialize the random state. TYPE: `int, defaults to 0` DEFAULT: `0`

Source code in smac/random_design/probability_design.py

    self._probability = probability
    self._factor = factor

next_iteration #

next_iteration() -> None

Sets the probability to the current value multiplied by factor.
