Struct Activity 

pub struct Activity {
    pub values: Vec<f64>,
}

One activity value per site.

Fields

values: Vec<f64>

Steps of memory remaining at each site.

Implementations

impl Activity

pub fn new(sites: usize) -> Self

A lattice that remembers nothing.

pub fn is_quiet(&self) -> bool

Whether any site remembers anything.

pub fn decay(&mut self)

Take one step off every site’s memory.

pub fn refresh(&mut self, site: usize, max_activity: f64)

Give a site the full memory a type states.

pub fn neighbourhood_mean( &self, lattice: &Lattice, site: usize, label: u32, ) -> f64

Geometric mean of the activity over the sites of label around site, counting the site itself.

Zero when any of them has forgotten, which is what makes the memory a front. A site whose cell has no other site nearby reads its own value.

Trait Implementations

impl Clone for Activity

fn clone(&self) -> Activity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Activity

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
