Struct Function

pub struct Function { /* private fields */ }

A representation of a f64 based distance matrix.

Implementations

impl Function

pub fn new(fun: fn(Vec<f64>) -> Result<f64, FunctionError>) -> Self

Create a new function.

Arguments

• fun - The function that should be computed in this struct.

Examples

use genetic_algorithm_fn::function;

let function_to_optimize = function::Function::new(
    |x| match x.len() {
        3 => Ok(x[0] * x[1] * x[2]),
        _ => Err(function::FunctionError::WrongNumberOfEntries {
            actual_number_of_entries: x.len(),
            expected_number_of_entries: 3,
        }),
    }
);

pub fn get_function_value( &self, function_values: Vec<f64>, ) -> Result<f64, FunctionError>

Compute the function value for a Solution.

Arguments

• solution - The solution for which the function value should be computed.

Examples

use genetic_algorithm_fn::function;

let function_to_optimize = function::Function::new(
    |x| match x.len() {
        3 => Ok(x[0] * x[1] * x[2]),
        _ => Err(function::FunctionError::WrongNumberOfEntries {
            actual_number_of_entries: x.len(),
            expected_number_of_entries: 3,
        }),
    }
);
println!("{}", function_to_optimize.get_function_value(vec![3.0, 4.0, 5.0]).unwrap());

Trait Implementations

impl Debug for Function
