Interface for beta update methods (NonlinearConjugateGradient)

Example

#[cfg(feature = "serde1")]
use serde::{Deserialize, Serialize};

#[cfg_attr(feature = "serde1", derive(Serialize, Deserialize))]
struct MyBetaMethod {}

impl<G, P, F> NLCGBetaUpdate<G, P, F> for MyBetaMethod
where
    F: ArgminFloat,
{
    fn update(&self, dfk: &G, dfk1: &G, p_k: &P) -> F {
        // Compute updated beta
    }
}
