Struct SmoothedLoadOptimization

pub struct SmoothedLoadOptimization<T> {
    pub d: i32,
    pub t_end: i32,
    pub bounds: Vec<T>,
    pub switching_cost: Vec<f64>,
    pub hitting_cost: Vec<f64>,
    pub load: Vec<T>,
}

Smoothed Load Optimization (SLO).

• SSCO
• hitting costs are time independent and linear in some incoming load

Fields

d: i32

Number of dimensions.

t_end: i32

Finite, positive time horizon.

bounds: Vec<T>

Vector of upper bounds of each dimension.

switching_cost: Vec<f64>

Vector of positive real constants resembling the switching cost of each dimension (strictly ascending). Dimensions must be efficient, i.e. there must not be dimensions with a higher switching and higher hitting cost than onether dimension.

hitting_cost: Vec<f64>

Time-independent cost of each dimension (strictly descending).

load: Vec<T>

Non-negative load at each time step.
