Struct FuzzySet 

pub struct FuzzySet {
    pub universe_size: usize,
    pub membership: Vec<f64>,
}

A fuzzy set over a universe represented as a list of (element, degree) pairs. Degrees are in [0, 1].

Fields

universe_size: usize

membership: Vec<f64>

membership[i] ∈ [0.0, 1.0]

Implementations

impl FuzzySet

pub fn new(universe_size: usize) -> Self

Create a crisp empty fuzzy set over a universe of the given size.

pub fn set(&mut self, i: usize, degree: f64)

Set the membership degree for element i (clamped to [0,1]).

pub fn get(&self, i: usize) -> f64

Get the membership degree for element i.

pub fn alpha_cut(&self, alpha: f64) -> Vec<usize>

α-cut: returns a crisp set of elements with membership ≥ α.

pub fn strong_alpha_cut(&self, alpha: f64) -> Vec<usize>

Strong α-cut: elements with membership > α.

pub fn complement(&self) -> FuzzySet

Fuzzy complement using standard negation: 1 − μ(x).

pub fn height(&self) -> f64

Height of the fuzzy set: max membership degree.

pub fn support(&self) -> Vec<usize>

Support: indices with membership > 0.

pub fn core(&self) -> Vec<usize>

Core: indices with membership = 1.

pub fn is_normal(&self) -> bool

Is the fuzzy set normal (height = 1)?

Trait Implementations

impl Clone for FuzzySet

fn clone(&self) -> FuzzySet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuzzySet

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

Formats the value using the given formatter.
