Algorithm 1: Mapping particle to cloudlet placement scheme

Input: Paticle $P_i^t$.

Output: Cloudlet placement scheme $\mathbf{\omega }$.

1 begin

2  foreach  ${\omega }_{i,j}\in \mathbf{\omega }$ do

3    ${\omega }_{i,j}=0$;

4  end

5  foreach  $p_{i,j}^t\in {\mathit{P}}_i^t$ do

6    ${\omega }_{j,p_{i,j}^t}=1$;

7  end

8  return  $\mathbf{\omega }$

9  end
