Start
Initialize the Grasshopper Population (n) and maximum number of
iteration (I), cmax, cmin
Calculate the fitness of each search agent
Define the best search agent (T)
No i<I
Display the best solutions Yes
C = cmax-i*( cmax-cmin)/I
End
J<n
Yes
No
Update the position of the search agent by Eq.19
J = j+1
Calculate the fitness of each search agent
Update T if there is a better solution
i = i+1

I
where c i ; c f are the initial and final values of the parameters c, they are
adjusted as 1 and 0.00001 respectively. i, I are the current iteration and the
-
maximum number of iterations respectively. Chaos is the chaotic map.
