Struct ProblemView 

Source
pub struct ProblemView<'a> {
    pub q: &'a CscMatrix,
    pub a: &'a CscMatrix,
    pub c: &'a [f64],
    pub b: &'a [f64],

    pub eliminated_cols: &'a [bool],
}
Expand description

KKT 計算に必要な要素だけを参照する軽量 view。

eliminated_cols[j] == true の col は presolve が物理削除した EmptyCol で、 postsolve が x[j]=val を埋め戻したあとの original space stationarity 評価から除外する (bd=0 慣例で r=0 になる前提)。reduced space (IPM 内部) では &[] を渡す: 削除済み col は構造的に存在しないため。長さ != bounds.len() の slice は無視する。
