The GA Playground: Ackley's Function
A widely used multimodal test function
Formulation:
Minimize:
f(x) = 20+e-20*exp(-0.2*(sqrt((1/n)*sum(x(i)^2))-exp((1/n)*sum(cos(2*Pi*x(i)))
-32.768 <= x(i) <= 32.768.
global minimum
f(x) = 0
x(i) = 0, i=1:n
Problem Specific Notes:
- The problem definition file is Ackley.par
- The file defines a 10-dimensions problem (n=10)
- The dimension can be changed by modifying he "Number of Genes" parameter
