Trait Problem 

pub trait Problem {
    type State;

    // Required methods
    fn initial_state(&self) -> Self::State;
    fn energy(&self, state: &Self::State) -> f64;
    fn new_state(&self, state: &Self::State) -> Self::State;
}

A problem represents something to be solved using simulated annealing, and provides methods to calculate the energy of a state and generate new states.

Required Associated Types

type State

Required Methods

fn initial_state(&self) -> Self::State

This function should generate an initial state for the problem.

fn energy(&self, state: &Self::State) -> f64

This function should calculate the energy of a given state, as a number between 0.0 and 1.0.

Lower energy means the state is more optimal - simulated annealing will try to find a state with the lowest energy.

fn new_state(&self, state: &Self::State) -> Self::State

This function should provide a new state, given the previous state.
