Struct tg4_mixer::functions::Sigmoid

pub struct Sigmoid {
    pub max_points: Decimal,
    pub p: Decimal,
    pub s: Decimal,
    /* private fields */
}

Sigmoid function. f(x) = 1 / (1 + e^-x). Fitting the sigmoid-like function from the PoE white-paper: f(x) = r_max * (2 / (1 + e ^(-s * x^p) - 1)

Fields

max_points: Decimal

p: Decimal

s: Decimal

Implementations

impl Sigmoid

pub fn new(
    max_points: Uint64,
    p: StdDecimal,
    s: StdDecimal
) -> Result<Self, ContractError>

Trait Implementations

impl PoEFunction for Sigmoid

fn mix(&self, stake: u64, engagement: u64) -> Result<u64, ContractError>

Returns the points based on the amount of stake and engagement points. f(x) from the README.
