A minimization of a function defined on 20 dimensional space
y = 20 + {(x_1)^2 - cos(2pi*(x_1))} + {(x_2)^2 - cos(2pi*(x_2))} + ... + + {(x_20)^2 - cos(2pi*(x_20))} all x_i from -5.12 to 5.12

(i) An example of result - 5 different runs with a same condition ... By Zanevich Ekaterina

A minimization of 2-dimensional function


y = 20 + (x^2 - cos(2pi*x) => 2-D version of the above 21-D function
(i) First, without mutation ... By Zanevich Ekaterina



Sometimes chromosomes are trapped into local minimum without mutation!




(ii) Then with mutation ... By Zaykova Ilona







Yet other 2-D functions
(i) y = x^4 - 5x^3 - 6x^2 + 8x +15 ... By Tsaruk Alexandr




(ii) y = x^4 - 5x^3 - 6x^2 + 8x +15 ... By Syhover Artiom



Chromosomes mistakenly recognized local minimum as global, though.
