Struct Objective 

pub struct Objective {
    pub sense: Sense,
    pub expr: LinExpr,
    pub name: Option<String>,
    pub priority: Option<u32>,
}

Represents an objective function in a model.

Contains the linear expression to optimize, the optimization sense (min/max), an optional name, and an optional priority (useful for multi-objective problems).

Examples

let x = model.add_var().finish(); // VarId
let objective = Objective::maximize(3.0 * x).name("Profit");

Fields

sense: Sense

Whether to minimize or maximize the objective.

expr: LinExpr

The linear expression representing the objective.

name: Option<String>

Optional human-readable name.

priority: Option<u32>

Optional priority for multi-objective optimization (not used)

Implementations

impl Objective

pub fn minimize(expr: LinExpr) -> ObjectiveBuilder

Creates a minimization objective.

Returns an ObjectiveBuilder to optionally set name or priority.

Example

let x = model.add_var().finish(); // VarId
let obj = Objective::minimize(3.0 * x).name("Cost");

pub fn maximize(expr: LinExpr) -> ObjectiveBuilder

Creates a maximization objective.

Returns an ObjectiveBuilder to optionally set name or priority.

Example

let x = model.add_var().finish(); // VarId
let obj = Objective::maximize(3.0 * x).name("Profit");

Trait Implementations
