Algorithm 1 Pseudo-code of SSD

Input: ${\mathsf{\theta }}_{\mathrm{i}}$,${ \mathsf{\mu }}_{\mathrm{i}}$, epochs Output: $\mathsf{\theta }$   1.For i in range (epochs):   2.L($\mathsf{\theta }$) = 1, ${\mathrm{b}}^2$−ac $\ge$ 0,   3.$\mathsf{\theta }$ = ${\mathsf{\theta }}_{\mathrm{i}}-\mathrm{w}$ Return $\mathsf{\theta }$
