Struct ViolationSummary 

pub struct ViolationSummary {
    pub total_violation: f64,
    pub max_violation: f64,
    pub n_violated: usize,
    pub violations: Vec<f64>,
}

Summary of constraint violations for a single candidate solution.

Violations are computed as max(0, g_i(x)) for inequality constraints (g_i(x) <= 0) and |h_j(x)| for equality constraints.

Fields

total_violation: f64

L1 sum of constraint violations.

max_violation: f64

Maximum single-constraint violation.

n_violated: usize

Number of violated constraints.

violations: Vec<f64>

Per-constraint violations (non-negative).

Implementations

impl ViolationSummary

pub fn new(violations: Vec<f64>) -> Self

Create a ViolationSummary from a vector of violation amounts.

Arguments

• violations — Non-negative violation per constraint. For inequality g_i(x) <= 0: pass max(0, g_i(x)). For equality h_j(x) = 0: pass |h_j(x)|.

pub fn is_feasible(&self) -> bool

Returns true if the solution is strictly feasible (all violations zero).

pub fn is_approximately_feasible(&self, tol: f64) -> bool

Returns true if the solution is approximately feasible within tol.

pub fn l2_norm(&self) -> f64

Compute the L2 (sum-of-squares) violation norm.

Trait Implementations

impl Clone for ViolationSummary

fn clone(&self) -> ViolationSummary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ViolationSummary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ViolationSummary

fn eq(&self, other: &ViolationSummary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
