Struct Rastrigin 

pub struct Rastrigin {
    pub a: f64,
}

Rastrigin function optimization (multimodal function)

Fields

a: f64

Parameter a (usually 10.0).

Trait Implementations

impl CostFunction for Rastrigin

type Output = f64

Type of the return value of the cost function

type Param = ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>

Type of the parameter vector

fn cost(&self, param: &Self::Param) -> Result<Self::Output, Error>

Compute cost function

fn bulk_cost<P>(&self, params: &[P]) -> Result<Vec<Self::Output>, Error>

where P: Borrow<Self::Param> + SyncAlias, Self::Output: SendAlias, Self: SyncAlias,

Compute cost in bulk. If the rayon feature is enabled, multiple calls to cost will be run in parallel using rayon, otherwise they will execute sequentially. If the rayon feature is enabled, parallelization can still be turned off by overwriting parallelize to return false. This can be useful in cases where it is preferable to parallelize only certain parts. Note that even if parallelize is set to false, the parameter vectors and the problem are still required to be Send and Sync. Those bounds are linked to the rayon feature. This method can be overwritten.

fn parallelize(&self) -> bool

Indicates whether to parallelize calls to cost when using bulk_cost. By default returns true, but can be set manually to false if needed. This allows users to turn off parallelization for certain traits implemented on their problem. Note that parallelization requires the rayon feature to be enabled, otherwise calls to cost will be executed sequentially independent of how parallelize is set.

impl Default for Rastrigin

fn default() -> Self

Returns the “default value” for a type.
