\[
q = \frac{1}{2} \max \left\{  \frac {\normvec{L_0}^2 + \normvec{L_3}^2 } { \alpha_0 },
                        \frac {\normvec{L_1}^2 + \normvec{L_0}^2 } { \alpha_1 },
                        \frac {\normvec{L_2}^2 + \normvec{L_1}^2 } { \alpha_2 },
                        \frac {\normvec{L_3}^2 + \normvec{L_2}^2 } { \alpha_3 } 
                \right\}
\]

Note that if $\alpha_i< DBL\_MIN$, we set $q = DBL\_MAX$.
