Trait for multi-objective function evaluation

Required Methods

fn num_objectives(&self) -> usize

Number of objectives

fn num_variables(&self) -> usize

Number of decision variables

fn evaluate(&self, variables: &[T]) -> Vec<T>

Evaluate all objectives for given variables

fn variable_bounds(&self) -> Vec<(T, T)>

Get variable bounds (min, max) for each variable

Provided Methods

fn evaluate_constraints(&self, _variables: &[T]) -> Vec<T>

Evaluate constraints (return violations, ≤ 0 means feasible)

fn ideal_point(&self) -> Option<Vec<T>>

Get ideal point (best possible values for each objective)

fn nadir_point(&self) -> Option<Vec<T>>

Get nadir point (worst values in current Pareto set)
