Struct DTLZ1Problem

pub struct DTLZ1Problem { /* private fields */ }

Test problem DTLZ1 from K.Deb,L. Thiele,M. Laumanns,and E. Zitzler, “Scalable test problems for evolutionary multi-objective optimization”

Implementations

impl DTLZ1Problem

pub fn create( n_vars: usize, n_objectives: usize, invert: bool, ) -> Result<Problem, OError>

Create the problem for the optimisation.

Arguments:

• n_vars: The number of variables.
• n_objectives: The number of objectives.
• invert: Whether to invert the problem based on Section VIIIA of Jain and Deb (2014)’s paper.

returns: Result<Problem, OError>

Trait Implementations

impl Debug for DTLZ1Problem

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

Formats the value using the given formatter.

impl Evaluator for DTLZ1Problem

fn evaluate(&self, ind: &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.
