Maximum use of particle swarm optimization algorithm to find the following
multivariate function: f (x, y) = x* cos (2* pi* y)+ y* sin (2* pi* x)
-2≤x≤2,-2 ≤y≤2
Required output optimal solution, x and y values corresponding to the optimal
solution, and the PSO iteration fitness function evolution curve.
