public class RouletteWheelSelection : ISelectionMethod
The algorithm selects chromosomes to the new generation according to their fitness values - the more fitness value chromosome has, the more chances it has to become member of new generation. Each chromosome can be selected several times to the new generation.
The "roulette's wheel" is divided into sectors, which size is proportional to the fitness values of chromosomes - the size of the wheel is the sum of all fitness values, size of each sector equals to fitness value of chromosome.
