BlockObjective

Struct BlockObjective 

Source
pub struct BlockObjective<'a, O> {
    pub full_objective: &'a mut O,
    pub full_beta: Vec<f64>,
    pub block: Range<usize>,
}
Expand description

Objective по одному блоку коэффициентов при фиксированных остальных блоках.

Оборачивает полный objective и проецирует вызовы на диапазон одного параметрического блока, копируя коэффициенты блока в общий full_beta перед вычислением.

Fields§

§full_objective: &'a mut O

Полный objective.

§full_beta: Vec<f64>

Текущий полный beta-вектор.

§block: Range<usize>

Диапазон оптимизируемого блока.
