Each function was tested in 10, 20, and 30 dimensions. The maxi-
mum number of iterations was set to 1000, 1500, and 2000, correspond-
ing to the dimensions 10, 20, and 30, respectively. Different population
sizes were used for each function with different dimensions: 20, 40, 80,
and 160. A linearly decreasing inertia weight was used that started at 0.9
and ended at 0.4, with acceleration constants ϕ of 2.0 for each (p − x)
term. V
max
and X
max
were set to be equal, with values identical to those in
the previous section. A total of 50 runs for each experimental setting
were conducted.
