Struct LpSolution 

pub struct LpSolution {
    pub objective: f64,
    pub primal: Vec<f64>,
    pub dual: Vec<f64>,
    pub reduced_costs: Vec<f64>,
    pub iterations: u64,
    pub solve_time_seconds: f64,
}

Complete solution from a successful LP solve.

All values are in the original (unscaled) problem space. Dual values are pre-normalized to the canonical sign convention defined in Solver Abstraction SS8 before this struct is returned – solver-specific sign differences are resolved within the crate::SolverInterface implementation.

See Solver Interface Trait SS4.1.

Fields

objective: f64

Optimal objective value (minimization sense).

primal: Vec<f64>

Primal variable values, indexed by column (length equals num_cols).

dual: Vec<f64>

Dual multipliers (shadow prices), indexed by row (length equals num_rows). Normalized to canonical sign convention.

reduced_costs: Vec<f64>

Reduced costs, indexed by column (length equals num_cols).

iterations: u64

Number of simplex iterations performed for this solve.

solve_time_seconds: f64

Wall-clock solve time in seconds (excluding retry overhead).
