Algorithm 1 Optimal PSM geometry

Input: Parameter search space $\Theta$

Output: Optimal parameter vector ${\theta }^{*}$ 1:for  $i=1,\cdots ,|\Theta |$  do 2:    $\theta \leftarrow {\Theta }_i$       ▹${\Theta }_i$ is ith element of $\Theta$ 3:    $J_i\leftarrow J(\theta )$, where $J(\theta )$ is given by (20) and $\tilde{P}(x,y,t)$ is given by (29) 4:    $J_i\leftarrow J_i+J(\theta )$, where $J(\theta )$ is given by (20) and $\tilde{P}(x,y,t)$ is given by (33) 5:    $J_i\leftarrow J_i+J(\theta )$, where $J(\theta )$ is given by (20) and $\tilde{P}(x,y,t)$ is given by (34) 6:end for 7:$i^{*}\leftarrow {min}_i\left\{J_i\right\}$ 8:${\theta }^{*}\leftarrow {\theta }_{i^{*}}$, 9:return  ${\theta }^{*}$
