 ## Description
 A simple genetic algorithm where each genome / individual is a single process.
 
-The crossover implementation can only handle populations which are divisible by four.
-Other populations will also be processed, but mixed up with simple cloned individuals. If
-crossover isn't enabled there are no restrictions.
