This trait defines an individual of a population in the genetic algorithm. It defines the fitness and mutation functions and the type of the individual representation.

Associated Types

`type ProblemSize: Default + Send + Sync`

The type that represents the problem size of the genotype. For example, in the N Queens problem the size of the ProblemSize is a numeric type (the number of queens).

Required methods

`fn iter(&self) -> Iter<T>`

Returns an iterator over the genes of the individual.

`fn into_iter(self) -> IntoIter<T>`

Consumes the individual into an iterator over its genes.

`fn generate(size: &Self::ProblemSize) -> Self`

Randomly initiailzes an individual.

`fn fitness(&self) -> f64`

Returns a fitness value for an individual.

`fn mutate(&mut self, rgen: &mut SmallRng, index: usize)`

Defines the manner in which an individual is mutated when an elemennt of the individual is selected to mutate.

`fn is_solution(&self, fitness: f64) -> bool`

Defines if an individual is a valid solution to the problem.

Provided methods

`fn fix(&mut self)`

Fix the individual to satisfy the problem restrictions. The default implementation is to remain the individual unmodified always.
