Genetic Algorithms: Can my Fitness Function be too complicated?
On a Genetic Algorithm, would it be correct to make the Fitness Function something other than a mathematical ecuation? Could it have a recursive function and a loop inside of it?
The thing is I'm evaluating if I can work with Genetic Algorithms for…

Java Simulated Annealing Acceptance Probability
I have a program implementing simulated annealing. I'm having a problem with the acceptance probability, probably due to my lack of understanding of why raising euler's number to the power of (energy - energy') is useful.
The probability is always…
