Trait ew::tools::statistics::StatFunctionsGoal

pub trait StatFunctionsGoal {
    fn get_average_goal(&self) -> Option<f64>;
    fn get_standard_deviation_goal(&self) -> Option<f64>;
}

The trait contains methods for calculate goal function statistics for Vec<Option<Solution>> type Solution = (T, GoalValue);

Required methods

fn get_average_goal(&self) -> Option<f64>

Calculate an average of goal function. Returns None if self is empty or self contains None only.

fn get_standard_deviation_goal(&self) -> Option<f64>

Calculate a standard deviation of goal function. Returns None if length of self less 2 or self contains None only.
