Can we benefit the linear relation between $\sigma$ and best convergence speed in $(\mu,\lambda)$-ES and $(\mu+\lambda)$-ES?
$(\mu,\lambda)$-ES and $(\mu+\lambda)$-ES are two well-known Evolution Strategies. One variant of these algorithms is when we set a constant value for $\sigma$ and generate off-springs for $x$ as:
$$
