Struct ZTD2Problem

pub struct ZTD2Problem { /* private fields */ }

Problem #2 from Zitzler et al. (2000)

Implementations

impl ZTD2Problem

pub fn create(n: usize) -> Result<Problem, OError>

Create the problem for the optimisation.

Arguments:

• n: The number of variables.

pub fn f1(x: &[f64]) -> f64

The first objective function.

pub fn f2(&self, x: &[f64]) -> f64

The second objective function.

Trait Implementations

impl Debug for ZTD2Problem

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

Formats the value using the given formatter.

impl Evaluator for ZTD2Problem

fn evaluate(&self, i: &Individual) -> Result<EvaluationResult, Box<dyn Error>>

A custom-defined function to use to assess the constraint and objective. When a new offspring is generated via crossover and mutation, new variables (or solutions) are assigned to it and the problem constraints and objective need to be evaluated. This function must return all the values for all the objectives and constraints set on the problem. An algorithm will return an error if the function fails to do so.
