}Expand description
A box-constrained, real-valued multi-objective minimization problem.
All objectives are minimized (negate any to be maximized). The
multi-objective optimizers (NsgaII, NsgaIII, SmsEmoa) return a
Pareto front rather than a single solution. As with Problem, a
non-finite objective value marks a point as infeasible — it is dominated by
every feasible point.
Required Methods§
Sourcefn bounds(&self) -> &[Bound] ⓘ
fn bounds(&self) -> &[Bound] ⓘ
Per-variable inclusive bounds, length MultiProblem::dim.
Sourcefn n_objectives(&self) -> usize
fn n_objectives(&self) -> usize
Number of objectives (≥ 2 for a genuine multi-objective problem).
Sourcefn objectives(&self, x: &[f64]) -> Vec<f64>
fn objectives(&self, x: &[f64]) -> Vec<f64>
The objective vector to minimize, length MultiProblem::n_objectives.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
