r Number of variables: n variables.

r Definition:

 

 

r Search domain: 0 ≤ x_i ≤ π, i = 1, 2, . . . , n.

r Number of local minima: several local minima.

r The global minima:          at n=2, f(x^*) = -1.8013.

                                                     at n=5, f(x^*) = --4.687658.

                                                     at n=10, f(x^*) = -9.66015.
