Optimal Allocation and Control of Magnetorheological Dampers for Enhancing Seismic Performance of the Adjacent Structures Using Whale Optimization Algorithm

Table 2

The pseudocode of Step 9 of the design process.

---

Update each position X_i with the following steps:

Update the algorithm parameters including a, b, A, C, l, and p defined in Section 3

Judge whether p < 0.5

If yes,

   Judge whether , which is defined in Section 3

   If yes,

     randomly determine a position in the range of the current population, and update the position Xi according to equation (19)

   else

     update the position Xi based on according to equation (14)

   end

else

   conduct spiral position updating according to equation (17)

end

Judge whether every code of the position X_i is within the predefined value ranges

If yes,

   keep the position X_i

else

   replace the code of the position X_i with the corresponding limit value

end

t = t + 1
