Variation of the objective function ${\mathcal{J}}_a$: a over the $\mathit{\alpha }/{\mathit{\alpha }}^{\text{ref}}$ space in systole, when ${\mathit{\alpha }}^{\text{ref}}>0$, and b over the $\mathit{\alpha }$ space in diastole, when ${\mathit{\alpha }}^{\text{ref}}=0$. White dots indicate positions of the minima for each step
