Algorithm 1: Coarser pseudocode for the proposed methodology

Input: structure information from the FEM analysis, number of sensors $m$ Output: optimal locations of the sensors Get the random binary matrix for the sensor’s placement $X_{iϵ\left[\mathrm{0,1}\right]}^t, t=\mathrm{1,2}\dots maxiter$ Calculate the multi-objective functions $F^t$ from the structural analysis Store the $X_{iϵ\left[\mathrm{0,1}\right]}^t$ and $F^t$ in the external archive when $t=1$ Update the particle’s position using the hypergraphed PSO Repeat the step 2 and 3 for $t=2$ Use the Grey relation analysis (GRA) on the archived particles to select the non-dominated solution Update the archive If iterations are finished a. Stop Else b. Repeat step 2 and 3 End Select the single solution from the final archive using Fuzzy Decision modelling (FDM)
