pub trait Alter<C: Chromosome>: Send + Sync {
// Required method
fn alter(
&self,
population: &mut Population<C>,
generation: usize,
) -> Vec<Metric>;
}Expand description
This is the main trait that is used to define the different types of alterations that can be
performed on a Population. The Alter trait is used to define the alter method that is used
to perform the alteration on the Population. The alter method takes a mutable reference to
the Population and a generation number as parameters. The alter method returns a vector of
Metric objects that represent the metrics that were collected during the alteration process.
An ‘Alter’ in a traditional genetic algorithm is a process that modifies the Population of individuals in some way. This can include operations such as mutation or crossover. The goal of an alter is to introduce new genetic material into the population, which can help to improve the overall fitness of the population. In a genetic algorithm, the alter is typically performed on a subset of the population, rather than the entire population. This allows for more targeted modifications to be made, which can help to improve the overall performance of the algorithm. The alter is an important part of the genetic algorithm process, as it helps to ensure that the population remains diverse and that new genetic material is introduced into the population. This can help to improve the overall performance of the algorithm and ensure that the population remains healthy and diverse.
In radiate the Alter trait performs similar operations to a traditional genetic algorithm,
but it is designed to be more flexible and extensible. Because an Alter can be of type Mutate
or Crossover, it is abstracted out of those core traits into this trait.
