Function std_dev::regression::spiral::two_variable_optimization

pub fn two_variable_optimization(
    fitness_function: impl Fn([f64; 2]) -> f64,
    options: Options
) -> [f64; 2]

Available on crate feature regression only.

Samples points on a logarithmic spiral in the phase space of all possible straight lines.

See Options.

Can be used for models other than linear, as this just optimizes two floats according to fitness_function. The returned values are the best match.
